<Skin analysis and patch proposal system>

21 is a view showing a skin analysis and patch proposal system according to an embodiment of the present invention.

In the present invention, the term 'patch' may be a term encompassing various kinds of beauty products that can be attached to the user's skin. Illustratively, the patch may be a concept that includes both a mask pack, various pads attached to the skin, cosmetic articles, massage packs, micro needle patches, and the like. It may also be a concept that includes both beauty and medical supplies. Hereinafter, a micro needle patch will be described as an example for convenience of explanation.

In the present invention, the term 'skin property' may mean various factors that are essential for evaluating the skin. For example, the properties of the skin may mean any one of the degree of flushing of the skin, the degree of wrinkling of the skin, and the flatness of the skin.

At this time, the degree of redness of the skin means that the skin is reddish, and the more reddish the skin, the higher the degree of redness. The degree of redness of the skin can have meaning as an element to judge the color of the skin.

The degree of wrinkling of the skin may mean the degree to which the skin folds finely due to a decrease in elasticity of the skin. At this time, the degree of the wrinkles of the skin is high, which may mean that the area of the skin folded finely is large or the degree of folded finely is large.

On the other hand, the flatness of the skin may mean the roughness of the skin due to factors other than the bending due to the wrinkles of the skin. For example, the flatness of the skin may mean the roughness of the skin due to the pores, or the degree of ruggedness of the skin due to scratches, dots, scars, etc. in a specific area.

However, the above-mentioned attributes of the skin are merely illustrative, and the spirit of the present invention is not limited thereto. It is obvious that the skin can be used as an attribute of the skin of the present invention if it can represent the state of the skin.

In the present invention, the 'grade of skin' may be a value determined according to the necessity of management of the skin based on the above-mentioned property of the skin. Grades are, for example, four grades, which may include a zero grade that requires no special care, a first grade that requires general care, a second grade that requires professional care, and a third grade that is urgently needed. However, such classification of grades is exemplary and skin can be classified into more or less grades. At this time, the grade of the skin can be calculated by taking into consideration the above-mentioned properties of the skin in various ways.

In the present invention, the user terminal 400 may refer to various devices capable of receiving attribute values or skin ratings of the skin from the server 300. The user terminal 400 may be a portable terminal or a personal computer.

The user terminal 400 may include display means for displaying contents or the like, and input means for obtaining a user's input on the contents. At this time, the input means and the display means can be configured in various ways. For example, the input means may include, but is not limited to, a keyboard, a mouse, a trackball, a microphone, a button, a touch panel,

The user terminal 400 may transmit the tagging information of the micro needle patch 100 (hereinafter referred to as a patch) to the server 300. The patch 100 is equipped with a wireless communication chip 101 such as an NFC and can perform short-range communication with the user terminal 400. [

The server 300 receives the image of the skin to know the property value or the rating from the skin measurement device 200, and can determine an attribute value or a rating of the skin.

The skin measurement device 200 may acquire a user's skin image and transmit the skin image to the server 300. The skin measurement device 200 may transmit the skin image acquired by the skin measurement device 200 to the user terminal 40 and / or the server 300 in real time in cooperation with the user terminal 400.

FIG. 22 is a flowchart showing a patch suggestion method based on a skin analysis result according to an embodiment of the present invention.

Referring to FIG. 22, a patch proposal method based on a skin analysis result according to an embodiment includes a step of obtaining and transmitting a primary skin image using the skin measurement device 200 (S101), analyzing a primary skin image Step S102, and transmitting the analysis result of the primary skin image to the user terminal 400 (S103).

The step of acquiring and transmitting the primary skin image using the skin measurement device (S101) may be applied to the method of acquiring the skin image using the skin measurement device 200 described with reference to FIGS. The skin image may be at least one of a distant image, a frontal image, a close-up image, a tilted image, or a stereoscopic image.

In the step of analyzing the primary skin image (S102), the server 300 may analyze the skin condition using the skin image received from the skin measurement device 200. [ Specific methods for analyzing the skin condition will be described later.

The step S103 of transmitting the information to the user terminal 400 can transmit the information about the patch 100 determined to be suitable for skin improvement together with the result of analysis by the server 300. [

The server 300 can select the patch 100 that is determined to be most suitable for skin improvement as a result of analyzing the condition of the skin. Specifically, the server 300 can tabulate and store a list of usable patches 100 according to the extent of skin damage. Accordingly, when the skin level and the attribute are determined, the patch 100 most matching with the skin level and attribute can be selected.

Referring to FIG. 23, the server 300 may suggest information (740) of a usable patch together with a skin analysis result of the user. The user can be informed of his / her skin condition and available patch information by using the information output to the user terminal 400.

In addition to the patch 100 information, additional information 750 may also be provided. For example, cosmetic information or a dermatology hospital may be recommended.

Referring again to FIG. 22, after using the guided patch 100, the user can again measure the skin condition. The skin measurement device 200 can be used to acquire at least one of a long distance image, a frontal image, a close-up image, a tilted image, or a stereoscopic image in the same manner as the previously measured method. The skin measurement apparatus 200 may transmit the obtained secondary skin image to the server 300 (S104).

The server 300 may analyze the secondary skin image (S105). The server 300 can evaluate the degree of improvement of the secondary skin image. That is, if it is determined that the analysis result of the secondary skin image is improved based on the analysis result of the primary skin image, it can be determined that the patch 100 currently in use is effective. Therefore, it may be suggested to use the patch regularly at the same time as outputting the improved skin analysis result.

However, if the skin analysis results are not improved or deteriorated even after using the patch 100, the server 300 may suggest the next succeeding patch 100 in the list. Or if there is a user of the same pattern as the result of learning, the user may suggest a skin improved patch.

Fig. 24 is a modification of Fig. 22. Fig.

Referring to FIG. 24, the process of the server 300 analyzing the primary skin image and recommending the patch 100 to the user terminal 400 may be the same as described above.

When the user uses the recommended patch 100, the user terminal 400 may transmit the tagging information to the server 300 when the patch 100 is tagged on the user terminal 400 (S204). As described above, the patch 100 can communicate with the user terminal 400 by attaching the NFC.

The server 300 may extract information such as the manufacture date, the used capacity, and the usage time of the currently used patch 100 in the database using the tagging information and generate a timer (S205). The timer can be set as long as the use time of the patch 100 is used.

If the server 300 determines that the timer has expired, the server 300 may output an end-of-use alarm to remove the patch 100 from the user terminal 400 (S207). Thus, the user can attach the patch 100 for an accurate time.

Thereafter, the user can measure the skin condition using the skin measuring device again after a predetermined time has elapsed. The server 300 can evaluate the degree of improvement of the secondary skin image (S209). That is, if it is determined that the analysis result of the secondary skin image is improved based on the analysis result of the primary skin image, it can be determined that the patch 100 currently in use is effective. Accordingly, it is possible to propose using the patch periodically at the same time as outputting the improved skin analysis result (S210).

FIG. 25 is a configuration diagram of a skin condition evaluating apparatus according to an embodiment of the present invention, and FIG. 26 is a diagram for explaining a method of generating a skin recognizer according to an embodiment of the present invention.

Referring to FIG. 25, the server 300 may include a skin condition evaluation device 301. FIG. However, the present invention is not limited thereto, and the skin condition evaluating apparatus 301 may be provided in the skin measuring apparatus 200 or may be provided in the user terminal 400. [ Hereinafter, the skin condition evaluating device of the server analyzes the skin image to determine the skin condition.

The skin condition evaluating apparatus 301 may include a communication unit 303, a control unit 304, and a memory 302. [ Also, although not shown in the drawing, the skin condition evaluating apparatus 301 according to an embodiment of the present invention may further include an input / output unit, a program storage unit, and the like.

26, the controller 304 of the skin condition evaluating apparatus 301 according to an exemplary embodiment of the present invention includes one or more training skin members 331 and 332 for generating the first skin recognizer 331 and the second skin recognizer 332, An image 310 may be obtained from the user terminal 400 and / or the skin measurement device 200.

At this time, the training skin image 310 may have an attribute value for at least one attribute and a rating of the skin. In other words, the training skin image 310 is an image for the skin that already has its attribute value and rating, and may be the information used for the generation and / or training of the skin recognizer.

For example, in the case of the first training skin image 311, the attribute value 312 including the flushing degree, wrinkle degree and flatness of the skin image 311 and the skin grade 313 may be marked. In this case, the degree of flushing, the degree of wrinkling and the degree of flatness, respectively, may be numerical values indicating the strength of each property such as 0.1 and 0.8. Also, the skin may have a grade of 'first class' or 'third class' and one of the above four classes.

In addition to the attribute values for the three attributes described above, the attribute value 312 may include attribute values for skin age (for example, skin age 30 years), sex (male), race (for example, Asian), disease As shown in FIG. However, the present invention is not limited thereto.

The control unit 304 according to an embodiment of the present invention may acquire the training skin image 310 from the skin measurement device 200 or may acquire the training skin image 310 from the memory 302 of the skin condition evaluation device 301 have. For example, the control unit 304 may acquire a training skin image 310 from a medical history stored in a server of a specific dermatologist. At this time, the medical history stored in the dermatology server may be written by an expert (for example, a dermatologist). In other words, the training skin image 310 may be based on data that an expert has evaluated the skin. In addition, the control unit 304 may acquire the training skin image 310 from a history in which an attribute value or a rating of another skin image has been determined in the past.

The controller 304 according to an embodiment of the present invention may generate a first feature vector from each of the training skin images 310 obtained by the above-described process. For example, the control unit 304 may generate the first feature vector 321 from the first training skin image 311. At this time, the control unit 304 may generate the first feature vector 321 based on the image analysis on the skin image 311. [

For example, the control unit 304 can recognize the face region in the skin image 311 for more accurate evaluation of the skin condition, and will be described with reference to FIG. The control unit 304 can determine the face area in the image 510 by using the recognition method of contour ratio and the recognition method of contour.

The control unit 304 can generate the first feature vector 520 based on the image 511 corresponding to the recognized face area. In other words, the control unit 304 can generate the first feature vector 520 only from the image 511, which is the object of the state evaluation, except for the region not subject to the state evaluation in the skin image 510. [ Thus, the present invention can exclude the elements of inaccuracy of skin condition evaluation according to the acquisition state or method of image.

On the other hand, the controller 304 may generate the first feature vector by considering the physical quantity of at least one physical quantity of the skin or the environment in which the skin is exposed in the generation of the first feature vector.

Images only contain visual information. Thus, from the image, it may be difficult to obtain the rest of the information other than the visual information about the skin (for example, the elasticity of the skin, the moisture content of the skin, the thickness of the skin, the thickness of the makeup painted on the skin, etc.). The controller 304 according to an embodiment of the present invention may generate the first feature vector by considering at least one physical quantity of the skin in generating the first feature vector. The moisture information of the skin can be obtained illustratively from the skin measuring device according to the embodiment.

For example, when an image is acquired under a lighting condition of a specific color, the color of the skin on the image may be different from the color of the original skin. The controller 304 may generate the first feature vector by considering the physical quantity of the environment in which the skin is exposed in the generation of the first feature vector.

The attribute value 312 for at least one attribute of the skin may be in the form of a second feature vector 322. In other words, the training skin image 311 may be marked with a second feature vector 322 corresponding to an attribute value 312 for at least one attribute of the skin. Such a second feature vector 322 may be generated through a separate transformation process on the attribute value 312 for at least one attribute of the skin.

As described above, the first skin recognizer 331 includes a first feature vector corresponding to each of a plurality of images of the skin, generated by a machine learning technique, and a second feature vector corresponding to one or more attribute values of each of the plurality of skin The correlation between the second feature vectors, i.e., the mapping information of both of them.

The controller 304 according to an embodiment of the present invention then updates the second skin recognizer 332 based on the second feature vector 322 and the skin grade 313 included in the training skin image information, can do. The skin grade 313 may then be in the form of a third feature vector 323. In other words, the training skin image 311 may be marked with a third feature vector 323 corresponding to the skin level. The third feature vector 323 may also be generated through a separate conversion process for the skin class 313.

As described above, the second skin recognizer 332 also includes a second feature vector corresponding to one or more attribute values of each of the plurality of skin generated by the machine learning technique, and a second feature vector corresponding to the class of each of the plurality of skin The correlation between the three feature vectors, that is, the mapping information of the two.

The control unit 304 according to an embodiment of the present invention may be configured such that the second feature vector 322 and the skin class 313 (i.e., the third feature vector 323) The second skin recognizer 332 can be updated in such a manner that the data set of the recognizer 332 is updated. When the data set of the second skin recognizer 332 is composed of a plurality of coefficients as shown in Fig. 26, the control unit 304 controls the second feature vector 322 and the third feature vector 323, And adjusts the coefficients constituting the second skin recognizer 332 based on the second skin recognizer 332. [

The control unit 304 can acquire the second skin recognizer 332 that repeatedly obtains the second feature vector and the third feature vector and repeatedly updates the coefficients based thereon to provide a more accurate skin rating .
