CROSS-REFERENCES TO RELATED APPLICATIONS

This application claims priority from U.S. Provisional Patent Application No. 62/892,572 filed on 28 Aug 2019, incorporated herein by reference in its entirety.

TECHNICAL FIELD

The invention relates to a system, method and computer readable medium for entity parameter calculation.

BACKGROUND

Physical fitness refers to the extent a human body can be taken while carrying out physical tasks. Knowing the specifics can help to determine fitness level and consequently set realistic fitness goals, monitor progress and maintain motivation.

Generally, fitness is assessed in four key areas: aerobic fitness, muscular strength and endurance, flexibility, and body composition. Human body is composed of two types of tissues known as fat weight and lean weight. Fat weight is the fat stored in fat cells throughout the body. Lean weight includes all other tissues, such as organs, bones, blood, skin, and muscle. Over the years, there is a muscle loss in favor of fat gain. The muscle loss adversely affects human's physical function and personal appearance.

The deterioration in body composition (too little muscle and too much fat) is a major health risk associated with many medical problems including obesity, lower back pain, type II diabetes, various forms of cancer, high blood pressure, and heart disease. In fact, obesity contributes to at least half the chronic diseases in western society.

There are many ways to assess body composition, the most common are circumference and body fat percentage measurements.

Body fat measurement is important for determining fitness level as weight alone is not a clear indicator of good health because it does not distinguish between pounds that come from body fat and those that come from lean body mass or muscle.

Body fat percentage is crucial to know in order to maintain a healthy lifestyle. There are many techniques for body fat percentage measurement (some of which are based on determination of physical circumference of the measured entity), such as Underwater weighing, Whole-body air displacement plethysmography, Near-infrared interactance, Dual energy X-ray absorptiometry, Body average density measurement, Bioelectrical impedance analysis and Anthropometric methods.

The known techniques for circumference and body fat percentage measurements are expensive and inaccessible, and thus, there is a growing need for a new system and method for entity parameter calculation.

Bearing this in mind, attention is drawn to Figs 1A and IB, showing an exemplary form-fitting garment 10, in accordance with the presently disclosed subject matter.

As shown in figure 1A, the form- fitting garment 10 includes a reference marker 12 and stretchable features 14(1), 14(2), 14(3), 14(4) and 14(5).

The form-fitting garment 10 can be made from elastic, washable and durable fabric, such as but not limited to linen, hemp, cotton, ramie, wool, silk, bamboo, soya, tencel, viscose, leather, suede, metal or any suitable polymer material. Another non limiting example of a fabric is a polyester and polyolefin materials having moisture wicking and stretch characteristics. The form-fitting garment 10 may be a slim or skin tight T-shirt, vest, dress, strap, belt, patch, halterneck or the like of appropriate (fitted) size. In some cases, the front portion of the form-fitting garment 10 can be stretchable while the form-fitting garment's 10 back portion is not necessarily stretchable.

The reference marker 12 may have a reference marker size that is known and constant. The reference marker 12 can be made from an unstretchable material so that wearing the form-fitting garment 10 will not cause stretching thereof. Accordingly, the reference marker's 12 size and shape does not change, irrespective of the form fitting garment 10 being worn or not.

In some cases, the reference marker 12 may have reference marker size that is known and substantially constant. That is, wearing the form-fitting garment 10 may cause stretching thereof by an insignificant extent, as further detailed hereinbelow. For example, the reference marker 12 may stretch (e.g. over time, upon wearing of the form fitting garment 10, etc.) by up to five millimeters, or less.

The reference marker 12 may be located in any location on the form- fitting garment 10. It can be integrated in the form-fitting garment 10, forming one surface of fabric, or located on the exterior of the front portion or the exterior of the back portion thereof, or any other configuration as long as it is visible to a camera taking a picture of an entity wearing the form-fitting garment 10. For example, the reference marker 12 can be located on the form-fitting garment 10 using an Applique technique.

In some cases, the reference marker 12 may have a distinctive color compared to the form-fitting garment 10.

In some cases, the distinctiveness can be in the visible spectrum, and in such cases, the reference marker 12 may have a first color that is different than a second color of the form-fitting garment 10, so that it can be distinguished from the form- fitting garment 10.

In other cases, the distinctiveness can be in the non-visible spectrum, in such cases, the reference marker 12 may have a first color different than a second color of the form-fitting garment 10, in an invisible spectrum (while their color can be identical or not in the visible spectrum). Such structure may be used for IR imaging for example.

In some cases, the form-fitting garment 10 may have a distinctive color compared to background surroundings.

The stretchable features 14(1), 14(2), 14(3), 14(4) and 14(5) may have known feature horizontal widths along at least part of a length of the form- fitting garment 10 when unworn. Accordingly, the horizontal widths of the stretchable features at various points along the at least part of the length of the form-fitting garment 10 are known.

The stretchable features 14(1), 14(2), 14(3), 14(4) and 14(5) can be designed to stretch upon the form-fitting garment 10 being worn, giving rise to stretched features 14'(1), 14'(2), 14'(3), 14'(4) and 14'(5) having stretched horizontal widths along the at least part of a length of the form-fitting garment 10. Accordingly, the horizontal width of a given stretchable feature (e.g. 14'(2)) at a given point along the at least part of a length of the form- fitting garment 10 when being worn is larger than the horizontal width of the same given stretchable feature (e.g. 14(2)) at the same given point when the form-fitting garment 10 is unworn. For example, stretchable features 14(2) and 14(4) have known feature horizontal widths 15 at a given point on the form- fitting garment 10 when it is being unworn, as depicted in figure 1A, and stretched horizontal widths 15' at the same given point on the form-fitting garment 10 when it is being worn, as depicted in figure IB. It is to be noted that the stretched horizontal widths 15' are larger than the known feature horizontal widths 15. The stretchable features 14(1), 14(2), 14(3), 14(4) and 14(5) may be located in any location on the form-fitting garment 10. They can be integrated in the form-fitting garment 10, forming one surface of fabric, or located on the exterior of the front portion or the exterior of the back portion thereof, or any other configuration as long as they are visible to a camera taking a picture of an entity wearing the form-fitting garment 10.

Optionally, as shown in Figs 1A and IB, the reference marker 12 and the stretchable features 14(1), 14(2), 14(3), 14(4) and 14(5), are of a rectangular/quadratic shape but other shapes may be used. In some cases, the reference marker 12 and the stretchable features 14(1), 14(2), 14(3), 14(4) and 14(5) may be whole or fractions of geometric shape(s), pattern(s), picture(s), design(s), dot(s), line(s), logo(s), symbol(s) and the like.

As further detailed herein, inter alia with reference to Fig. 4, the reference marker 12 and the stretchable features 14(1), 14(2), 14(3), 14(4) and 14(5) enable calculation of at least one of:

(A) a circumference of an entity wearing the garment 10 utilizing at least (a) the reference marker size, and (b) at least one difference between a given stretched horizontal width and a respective known feature horizontal width of the feature horizontal widths; wherein upon the entity wearing the garment, the difference between the given stretched horizontal width and the respective known feature horizontal width of the feature horizontal widths is determined by capturing an image of the garment, including the reference marker and the stretchable feature, and analyzing the image or

(B) body fat percentage of the entity wearing the garment 10 utilizing at least (a) the reference marker size, and (b) the at least one given stretched horizontal width.

Turning to Fig. 2, there is shown a block diagram schematically illustrating one example of an environment 200 for performing an entity parameter calculation, in accordance with the presently disclosed subject matter. The environment 200 includes a user equipment 204, a user 206 wearing the form-fitting garment 10, a communication network 202 and an entity parameter calculation system 208.

The processing circuitry 302 comprises an entity parameter calculation module 304 configured to perform an entity parameter calculation process, as further detailed herein with respect to Pig. 4.

In some cases, the system for entity parameter calculation 208 comprises, or may be otherwise associated with, a data repository 306 (e.g. a database, a storage system, a memory including Read Only Memory - ROM, Random Access Memory - RAM, or any other type of memory, etc.) configured to store data, including inter alia user-related data relating to one or more users 206 wearing the form-fitting garment 10, and various data acquired from such users 206 (e.g. digital image/s of the user 206 wearing the form-fitting garment 10, physical details of the user 206 (such as age, gender, garment size of the garment 10 worn by the user 10, medical condition, fitness level or any other parameter representing a physiological characteristic thereof), body metrics of the user 206 (such as height, weight, circumference, BMI, body composition, etc.), contact details of the user 206 (such as phone number, email, residence address, social media accounts, etc.), etc.).

In some cases, data repository 306 can be further configured to enable retrieval and/or update and/or deletion of the stored data. It is to be noted that in some cases, data repository 306 can be distributed across multiple locations, whether within the entity parameter calculation system 208 and/or within the user equipment 204 and/or elsewhere. It is to be noted, that in some cases, the relevant information relating to the user 206 can be loaded into data repository 306 before taking a picture of user 206 wearing the form-fitting garment 10 (e.g. upon entering the system for entity parameter calculation 208 and/or periodically and/or upon the system for entity parameter calculation 208 requesting the information) or after.

Turning to Fig. 4, there is shown a flowchart illustrating one example of a sequence of operations carried out for performing an entity parameter calculation, in accordance with the presently disclosed subject matter.

For this purpose, the system for entity parameter calculation 208 (also referred to herein as “system”) can be configured to receive a digital image of a form-fitting garment 10 being worn (e.g. by a person whose entity parameter calculation is desired) (block 410). As indicated herein, inter alia with reference to Figs. 1A, IB, and 2, the form-fitting garment 10 has (a) a reference marker 12, having a reference marker size that is known and substantially constant, and (b) at least one stretchable feature 14(1), 14(2), 14(3), 14(4) or 14(5), having known feature horizontal widths along at least part of a length of the garment when unworn. Each of the at least one stretchable features (e.g. stretchable features 14(1), 14(2), 14(3), 14(4) or 14(5)) is designed to stretch upon the garment 10 being worn, giving rise to respective stretched features (e.g. stretched features 14'(1), 14'(2), 14'(3), 14'(4) or 14'(5) having stretched horizontal widths along the at least part of the length of the garment.

The digital image of the form-fitting garment 10 being worn can be acquired by a camera unit that may be comprised within the user equipment 204 or may be otherwise connected to it via a wired/wireless communication channel. The camera unit may be operated by the user 206 wearing the form-fitting garment 10 (i.e. for taking a self- portrait) or a third party (e.g. a camera unit with a timer feature, a selfie stick, mirror reflection, another person is taking the picture etc.).

The system 208 can be further configured to identify, within the digital image, the reference marker 12 and at least one of the stretchable features (e.g. stretchable feature 14(1), 14(2), 14(3), 14(4) or 14(5)) (block 420).

The identification of the reference marker 12 and the at least one stretchable feature 14(1), 14(2), 14(3), 14(4) or 14(5) within the digital image can be done for example by an automated pattern recognition technology (e.g. by utilizing digital image processing techniques). In such cases, optionally (e.g. in order to facilitate the pattern recognition), the user can be required to place the reference marker 12 within an ad hoc frame displayed on a user interface of the camera unit used for acquiring the digital image, before taking the picture of the form-fitting garment 10 being worn.

It is to be noted that in other cases, the system 208 is not required to identify the reference marker 12 within the digital image. In such cases, the operator of the camera unit is required to accurately place the reference marker 12 within an ad hoc frame displayed on a user interface of the camera unit used for acquiring the digital image, before taking the picture of the form-fitting garment 10 being worn. Accordingly, the identification of the reference marker by the system 208 is made redundant.

Optionally, the camera unit can be configured to automatically acquire the digital image, of the form- fitting garment 10 being worn, once the reference marker 12 has been aligned with the frame displayed on the user's interface thereof.

Moreover, the camera unit can be configured to assist the user to align the reference marker 12 with the frame displayed on the user interface of the camera unit by providing direction arrows for example.

The system 208 can be further configured to determine a conversion ratio utilizing pixels representing the reference marker 12 in the digital image and the reference marker size (block 430). The reference marker size may be known and constant, that is, its size (e.g. its cross-section, area, horizontal latitude, etc.) may be known in centimeters for example, or in any other measurement system (i.e. the International System of Units (SI), the imperial system, the United States customary units, etc.). The reference marker 12 can be designed to maintain its known original size (i.e. remain constant) irrespective of the form-fitting garment 10 being worn or not.

In some cases, the reference marker 12 may be represented by MxN pixels in the digital image, wherein M indicates number of pixels in horizontal line of the reference marker's 12 contour and N indicates number of pixels in vertical line thereof.

In other cases, the marker 12 may be represented in pixels merely by a one dimensional line that may be oriented in any direction on the form-fitting garment 10.

The conversion ratio may be determined utilizing the reference marker size and its representation in pixels (e.g. M pixels are equal to Y centimeters so that conversion ratio can be calculated therefrom). This way, any desired object in the form-fitting garment 10 (e.g. stretchable features 14(1), 14(2), 14(3), 14(4) or 14(5) or stretched features 14'(1), 14'(2), 14'(3), 14'(4) or 14'(5) ) may be converted from its pixel representation in the digital image to its corresponding metric representation for example.

It is to be noted that in some cases, the reference marker 12 can be designed to substantially maintain its known original size (i.e. remain substantially constant) upon the form-fitting garment 10 being worn. In these cases, the reference marker 12 may stretch by insignificant extent that will not affect the determination of the conversion ratio therefrom (e.g. by up to five millimeters or less).

The system 208 can be further configured to determine one or more conversions of one or more respective given stretched horizontal widths of the at least one stretchable feature 14(1), 14(2), 14(3), 14(4) or 14(5) identified in the digital image, converted using the conversion ratio (block 440).

The at least one stretchable feature 14(1), 14(2), 14(3), 14(4) or 14(5) may be stretched once the user 206 is wearing the form-fitting garment 10. The stretched feature 14'(1), 14'(2), 14'(3), 14'(4) or 14'(5) may have a stretched horizontal width that can be represented in pixels in the digital image. The stretched horizontal width can be converted into centimeters, for example, by utilizing the conversion ratio. This way, each stretched horizontal width along the at least part of the length of the garment 10 can have a corresponding converted width (i.e. conversions).

The system 208 can be further configured to calculate an entity parameter related to an entity wearing the garment 10, utilizing the conversions (block 450).

Calculating circumference of the entity:

In some cases, the entity parameter may be a circumference of the entity (i.e. user 206 wearing the form-fitting garment 10). In such cases, the circumference of the entity can be determined in various manners, some of which are exemplified herein:

In these cases, the circumference can be calculated by inputting the conversions and one or more input parameters associated with the entity into a classifier, wherein the classifier is configured to obtain the conversions and the input parameters and determine the respective circumference.

The input parameters may include at least one of: age, height, weight, garment size of the garment worn by the entity, or gender.

The classifier is trained using a training set including a plurality of records, each of the records having respective training input parameters, training conversions and a respective verified circumference measurement.

The training input parameters may include at least one of: age, height, weight, garment size of the garment worn by the entity, or gender.

The training conversions may be obtained from a conversions training data set obtained during previous measurements, or from external databases.

For example, the conversions training data set may consist of previously determined stretched horizontal widths along the at least part of the length of the form fitting garment 10 converted into centimeters by utilizing various conversion ratios.

The verified circumference measurements may be obtained from a verified circumference measurement training data set obtained during previous measurements, or from external databases.

For example, the verified circumference measurement training data set may consist of circumference measurements made by a dietician.

Looking at an exemplary record of the training set, it can comprise, for a given entity, its input parameters (e.g. the entity’s age and/or height and/or weight and/or garment size of the garment worn by the entity and/or gender), its conversions (e.g. stretched horizontal widths of stretchable feature/s along the at least part of the length of the form-fitting garment 10 converted into centimeters), and its verified circumference measurement (e.g. measured using a measurement device operated by a dietician).

Alternatively, or additionally, the circumference can be calculated by:

(A) determining at least one difference between (a) the conversions, and (b) respective known feature horizontal widths of the feature horizontal widths; and

(B) inputting the at least one difference and one or more input parameters associated with the entity into a classifier that is configured to obtain the at least one difference and the input parameters and determine the respective circumference.

In such cases, such a classifier is trained using a training set including a plurality of records, each of the records having respective training input parameters (e.g. age, height, weight, garment size of the garment worn by the entity, or gender), training difference and a respective verified circumference measurement.

The training difference may be obtained from a difference training data set obtained during previous measurements, or from external databases.

For example, the difference training data set may consist of previously determined differences between conversions of stretched horizontal widths along the at least part of the length of the form- fitting garment 10 into centimeters and respective known feature horizontal widths.

Looking at an exemplary record of the training set, it can comprise, for a given entity, its input parameters (e.g. the entity’s age and/or height and/or weight and/or garment size of the garment worn by the entity and/or gender), its differences (e.g. differences between conversions of stretched horizontal widths of stretchable feature/s along the at least part of the length of the form-fitting garment 10 worn by the entity into centimeters and respective known feature horizontal widths of the respective stretchable feature/s), and its verified circumference measurement (e.g. measured using a measurement device operated by a dietician).

Calculating Body Fat Percentage of the entity:

In some cases, the system 208 can be further configured to determine a body fat percentage of the entity using a formula, wherein the formula is configured to receive the circumference and the one or more input parameters and output the body fat percentage.

The formula may be a mathematical formula such as a U.S. Navy Formula, BMI formula, BMR formula, YMCA formula, BSA formula or any other suitable formula.

Having described various manners for determining the circumference of the entity, it is to be noted that in other cases, the entity parameter may be a body fat percentage of the entity (i.e. user 206 wearing the form-fitting garment 10). In such cases, the body fat percentage can be determined in various manners, some of which are exemplified herein:

In some cases, the body fat percentage may be calculated by inputting the conversions, and one or more input parameters into a classifier, wherein the classifier is configured to obtain the conversions and the input parameters and provide the body fat percentage.

In such cases, the classifier is trained using a training set including a plurality of records, each of the records having respective training input parameters (e.g. age, height, weight, garment size of the garment worn by the entity, or gender), training conversions and a respective verified body fat percentage measurement.

The verified body fat percentage measurements may be obtained from a body fat percentage training data set obtained during previous measurements, or from external databases.

For example, the verified body fat percentage measurement training data set may consist of body fat percentage measurements made by a dietician. Various measurement devices may be used by the dietician to measure body fat percentage such as Ultrasound devices, Dual-energy X-ray absorptiometry (DXA) scans (that have become a “gold standard” for the assessment of body composition in sports nutrition), Skinfold Calipers, etc.

Looking at an exemplary record of the training set, it can comprise, for a given entity, its input parameters (e.g. the entity’s age and/or height and/or weight and/or garment size of the garment worn by the entity and/or gender), its conversions (e.g. stretched horizontal widths of stretchable feature/s along the at least part of the length of the form- fitting garment 10 converted into centimeters), and its verified body fat percentage measurement (e.g. measured using a measurement device operated by a dietician).

Alternatively, or additionally, the body fat percentage can be calculated by:

(B) inputting the at least one difference and one or more input parameters associated with the entity into a classifier, wherein the classifier is configured to obtain the at least one difference and the input parameters and determine the respective body fat percentage.

In such cases, such a classifier is trained using a training set including a plurality of records, each of the records having respective training input parameters (e.g. age, height, weight, garment size of the garment worn by the entity, or gender), training difference and a respective verified body fat percentage measurement.

For example, the verified body fat percentage measurement training data set may consist of body fat percentage measurements made by a dietician.

Looking at an exemplary record of the training set, it can comprise, for a given entity, its input parameters (e.g. the entity’s age and/or height and/or weight and/or garment size of the garment worn by the entity and/or gender), its differences (e.g. differences between conversions of stretched horizontal widths of stretchable feature/s along the at least part of the length of the form-fitting garment 10 worn by the entity into centimeters and respective known feature horizontal widths of the respective stretchable feature/s), and its verified body fat percentage measurement (e.g. measured using a measurement device operated by a dietician).

Alternatively, or additionally, the body fat percentage can be calculated by determining a circumference of the entity and inputting the circumference and one or more input parameters associated with the entity into a classifier, wherein the classifier is configured to obtain the circumference and the input parameters and determine the respective body fat percentage.

The classifier is trained using a training set including a plurality of records, each of the records having respective training input parameters (e.g. age, height, weight, garment size of the garment worn by the entity, or gender), training circumference and a respective verified body fat percentage measurement.

The training circumference may be obtained from a circumference training data set obtained during previous measurements, or from external databases.

For example, the circumference measurement training data set may consist of circumference measurements made by a dietician.

Looking at an exemplary record of the training set, it can comprise, for a given entity, its input parameters (e.g. the entity’s age and/or height and/or weight and/or garment size of the garment worn by the entity and/or gender), its circumferences (e.g. measured using a measurement device operated by a dietician or calculated by one or more of the classifiers that are used to determine circumference as described hereinabove), and its verified body fat percentage measurement (e.g. measured using a measurement device operated by a dietician).

It is to be further noted that various calculation methods described hereinabove may be performed utilizing statistical techniques, e.g. Multiple linear regression (MLR).

In addition, the method described in the foregoing specification can be implemented utilizing a software debounce routine, or any other anomaly filtering method and/or technique, thereby at least reducing, if not eliminating, err calculations of the entity parameter(s).

Optionally, when reference is made herein to calculations that utilize measurements of stretched horizontal widths of stretchable feature(s) along the at least part of the length of the form-fitting garment 10 worn by the entity, the number of measurements can be any number of measurements higher than one. In case more than one measurement is used, each measurement is made at a different location along the length of the stretchable feature(s). In a specific non-limiting example, nine measurements can be used. In some cases, the stretched horizontal widths that are used, are the ones the correspond to those locations along pre-set portions (e.g. the waist area, the chest area, the basin area, etc.) along the length of the stretchable feature(s), that stretched more than other locations at the corresponding pre-set portion.

Optionally, the system 208 can take into account differences in the way men and women accumulate fat so that it's the calculation of the entity parameter(s) may differ between women and men. For instance, calculation for women may be based on measurements of three stretched horizontal widths of stretchable feature(s) along the at least part of the length of the form- fitting garment 10 while for men only two measurements of stretched horizontal widths may suffice.

In some cases, the entity parameter may be a body type of the entity wearing the form-fitting garment 10, thereby demonstrating one of the three known in the art body types: Ectomorph, Endomorph or Mesomorphic. For this purpose, the entity wearing the form-fitting garment 10 may provide the system 208 with at least one of the input parameters (e.g. height). The entity parameter calculation module 304 may be configured to calculate a width of the entity wearing the form-fitting garment 10 and utilize the width and the input parameters to determine the body type of the entity wearing the form-fitting garment 10.

In other cases, the entity parameter calculation module 304 may be configured to calculate a width of the entity wearing the form-fitting garment 10 and utilize the width to determine the body type of the entity wearing the form-fitting garment 10.

It is to be noted that in some cases, the system 208 can utilize historical and optionally current measurements of stretched horizontal widths in order to generate a two-dimensional or three-dimensional representation showing the progress/change of the entity wearing the form-fitting garment 10.

It is to be noted that, with reference to Fig. 4, some of the blocks can be integrated into a consolidated block or can be broken down to a few blocks and/or other blocks may be added. Furthermore, in some cases, the blocks can be performed in a different order than described herein (for example, block 440 can be performed before block 430, block 430 can be performed before block 420, block 420 can be performed before block 410, etc.). It is to be further noted that some of the blocks are optional.
