Abstract

The present invention refers to a model for transforming a mobile device into a tool for detecting skin ailments, where the mobile device captures an image of a user and applies an image processing technique, extracting the desired region and processing the image for obtaining a result. The model applies a questionnaire before performing the image processing so as to determine, along with the result of the image analysis, the skin care suggestions that better suit the needs of the user.

Description

TECHNOLOGY FOR THE SUPPORT TO THE SEMI-AUTOMATIC CHARACTERIZATION AND CLASSIFICATION OF DERMATOLOGICAL PECULITIES.

Technical Field of the invention: The present invention implemented by computer refers to the obtaining of images by means of a mobile device to identify the existence of an skin condition, through the analysis of images and a questionnaire of i assessment to the user, thus determining the percentage of affectation of said condition on the skin of the user; The images are captured by a mobile device and processed in the same mobile device where the process of implementing image processing algorithms is carried out, allowing the affectation to be characterized in a percentage way; once your i is detected, presence and additionally supported in a questionnaire that the user responds in real time, the device evaluates the answers given by the user allowing to establish parameters to later indicate to the user specific recommendations for the care of their skin. i! Background of the invention: There are more than 2000 diseases that can affect the skin, the most known or frequent are: Acne, Psoriasis, Vitiligo, hair loss (Alopecia), allergies (Eczema, Urticaria, Prurigos), infections (Piodermitis), ulcers , among many ptras. The early detection of them allows dermatologists to provide an adequate treatment, accurate and more likely to succeed.

For example, acne is one of the most common skin diseases, it affects I 70 to 80% of adolescents. Patients with acne can present a significant psychological morbidity and in some cases mortality and suicide There are different classifications of dermatological diseases. Of the According to their etiology, they can be classified as infectious, inflammatory, immunological and tumor. There is a great variety of dermatological diseases, where an important part of the medical evaluation that is carried out in order to recommend an adequate treatment is the determination of the extent that affects the surface of the skin. The determination of the extent of the disease helps dermatologists to be able to perform a I correct ^ dosing of the drugs that will be recommended for the treatment of the disease, besides that an important metric in the monitoring of the evolution in the patient, is the decrease of this affected area. j The majority of dermatological diseases are characterized by lesions that can be observed with the naked eye, so when they are captured using a digital capture device, these lesions continue to present themselves.

The digital treatment of images contemplates the processing and analysis of images. The processing is referred to the realization of transformations and to the restoration and improvement of the images. The analysis consists in the extraction of properties and characteristics of the images, as well as the classification and identification and the recognition of patterns. Digital image processing is the set of techniques that are applied to images in order to improve the quality or facilitate the search for information.

I The influence and impact that the use of digital image processing has had on the medical area is very relevant. The rapid progress in the medical reconstruction of images, and their associated developments to create tools to assist medical diagnostics, has propelled the field of medical image processing as one of the most important in this area.

Ii In order to extract information from an image, it is necessary to determine the specific characteristics that are sought in it. Some conditions dermatological, present lesions on the skin, whose characterization can be properly performed using various image processing techniques.

The integration of both components allows the development of a skin characterization model that determines the percentage of involvement observed in a captured image, in order to issue skin care recommendations.

I to the user, according to the results obtained and the illness that it presents.

Examples of devices for the analysis of skin conditions are described, for example, in the utility model MX / u / 2010/000282, which describes a device for evaluating the skin or hair of a person and based on this, recommend the most appropriate personal care product based on the evaluation. However, this invention is limited to the analysis of skin characteristics such as wrinkles, spots, color, uniformity of color, pores, roughness, brightness and freckles and based on the evaluated attributes, a recommendation is generated, this being of the nature of the skin care of the cosmetic area. The main difference with our invention is that the characterization of the diseases of the skin that are made, are supported by the questionnaire of variables and the recommendations that it makes are of support to the area ! dermatological Additionally, in the image that is captured for analysis, elements other than the user's skin may be observed, which will be eliminated through the process of selecting the region of interest, which eliminates the regions of the image where no skin is observed.

Brief description of the figure: Figure 1 presents the algorithm used for image processing.

Detailed description of the invention: When the user first accesses the application, they must register their personal data in order to use the application. You will be provided with access data that will be sent to the email account provided at the time of filling out the registration, with this information the user must identify himself in order to enter the system. The user selects on the mobile device the option to carry out a study where the first step is the completion of the assessment questionnaire, after having completed the questionnaire, we proceed to capture the image either with the camera of the device or a preloaded image that the user has stored in the device. Once the image has been selected, it is necessary to apply l the image processing algorithms to identify the parts that present the aené disease. With the analysis of the questionnaire and the result of the processing of the image, the invention will yield the final results where the user is told what actions to take for their health. Subsequently, the user can save the results in the device or send them to a web platform for storage and not overload the memory of the mobile device. The user has the option of being able to consult this information in said portal if he / she so wishes to verify the progress of the treatment that he / she has.

Claims

Claims A model of skin characterization in a mobile device to determine the percentage of skin involvement previously selected that presents I a questionnaire of specific variables of a dermatological condition to the user, provide recommendations and store the results remotely and locally: a) A method for characterizing the skin mentioned in point 1 by the discrimination of regions that are observed in an image to segment healthy skin areas from those that are not. b) A mobile device mentioned in point 1, including a device 1 digital optical by means of which one or several images are obtained where the patient's skin is observed, which will be processed by means of image processing algorithms. c) A method to determine the percentage of involvement in the skin mentioned in point 1 by analyzing an image previously captured through: i), Selection of the region of interest I) Image processing to increase the contrast in the areas to | sort out iiij Selection of sample area for training and characterization of specific lesions of a certain skin disease. iv) Segmentation of healthy skin areas of skin areas with lesions. v) Calculation of the percentage of involvement of skin lesions. vi) Graphic presentation of results d) Uh questionnaire of variables mentioned in point 1 that collects variables associated with the risk factors of a condition dermatological specific. e) Recommendations presented to the user mentioned in point 1, » directed to the care of the skin and personalized according to the results of percentage of affectation obtained and the data contained in the variable questionnaire. 6 ) l
