CAMPO DA INVENÇÃO FIELD OF INVENTION
[001] A presente invenção refere-se, de um modo geral, a um sistema e um método para análise de imagens de danos nos fios de cabelos e identificação de produtos para aplicação e cuidado dos fios de cabelos. Mais particularmente, esses novos sistema e método foram projetados e desenvolvidos para analisar imagens do estado dos cabelos, em especial os danos causados nos fios de cabelos, utilizando um conjunto de componentes e técnicas de processamento de imagens para, a partir disso, identificar um possível tratamento específico para os fios de cabelos, incluindo a indicação de produtos com base em uma gama de produtos disponíveis ao usuário. [001] The present invention generally refers to a system and method for analyzing images of damage to hair strands and identifying products for applying and caring for hair strands. More particularly, these new systems and methods were designed and developed to analyze images of the condition of hair, in particular the damage caused to hair strands, using a set of components and image processing techniques to, from this, identify a possible specific treatment for hair strands, including product recommendations based on a range of products available to the user.
ANTECEDENTES DA INVENÇÃO BACKGROUND OF THE INVENTION
[002] Existem no estado da técnica diversas maneiras de obter uma análise do estado do cabelo de um indivíduo para que, com isso, seja possível indicar um cuidado, ou até mesmo um determinado produto, que seja adequado para as condições específicas do cabelo daquele indivíduo. [002] There are, in the state of the art, several ways to obtain an analysis of the condition of an individual's hair so that, with this, it is possible to indicate a care, or even a certain product, that is suitable for the specific conditions of that person's hair. individual.
[003] Atualmente, para conduzir esse tipo de avaliação, é necessário a análise de uma amostra dos fios de cabelo por um profissional especializado e equipado, tal como um tricologista, capaz de identificar as condições dos fios de cabelo e, a partir daí, formular um tratamento para tratar os fios e danos identificados e chegar ao resultado desejado pelo usuário. [003] Currently, to conduct this type of assessment, it is necessary to analyze a sample of hair strands by a specialized and equipped professional, such as a trichologist, capable of identifying the condition of the hair strands and, from there, formulate a treatment to treat the strands and damage identified and achieve the result desired by the user.
[004] Ainda, para conduzir esse tipo de avaliação, o profissional pode utilizar diversos equipamentos específicos para auxiliar na visualização dos fios de cabelos e identificação das suas condições. Assim, é evidente que esse processo de avaliação e identificação dos danos e, consequentemente, os possíveis tratamentos a serem indicados é um trabalho relativamente complexo e com custo alto, sendo muitas vezes inviável para uma grande parte da população, considerando a especificidade dos equipamentos e da expertise dos profissionais necessários para obtenção de tal avaliação. [004] Furthermore, to conduct this type of evaluation, the professional can use various specific equipment to help visualize the hair strands and identify their conditions. Thus, it is clear that this process of evaluation and identification of damage and, consequently, the possible treatments to be indicated is a relatively complex and high-cost task, often unfeasible for a large part of the population, considering the specificity of the equipment and the expertise of the professionals necessary to obtain such an assessment.
[005] No intuito de tentar minimizar os custos e tempo, e dispensar, de certo modo, a necessidade imediata de um profissional com elevada experiência, foram desenvolvidos métodos e sistemas para que o próprio usuário ou vendedor de produtos realizasse a avaliação das características do cabelo, permitindo definir os produtos mais adequados para o tipo específico de cabelo do indivíduo. [005] In order to try to minimize costs and time, and dispense, in a certain way, with the immediate need for a highly experienced professional, methods and systems were developed so that the user or seller of products could carry out the evaluation of the characteristics of the product. hair, allowing you to define the most suitable products for the individual's specific hair type.
[006] Exemplos desse sistema e método podem ser encontrados no documento W02022109096A1 , onde é descrito um sistema e um método para análise de captura de imagens e aprendizagem de máquina para analisar uma imagem do usuário, essa imagem sendo dividida em regiões do cabelo para permitir que o modelo de aprendizagem de máquina classifique o cabelo do usuário e, posteriormente, gere uma recomendação de produto para o tipo de cabelo identificado através de um aplicativo em um dispositivo móvel. [006] Examples of this system and method can be found in document W02022109096A1, where a system and method for image capture analysis and machine learning to analyze a user image is described, that image being divided into hair regions to allow for the machine learning model to classify the user's hair and subsequently generate a product recommendation for the hair type identified through an application on a mobile device.
[007] Apesar de se mostrar funcional, observou-se que essa solução conhecida no estado da técnica continua apresentando a limitação de não conseguir realizar uma avaliação do estado, e principalmente, dos possíveis danos nos fios de cabelos, isso porque, o sistema e método revelados no estado da técnica propõem soluções limitadas a identificação das características gerais do cabelo, como por exemplo, se é seco, oleoso, liso, o nível de brilho, volume, frizz, cores, etc. e, ainda, de forma distanciada, ou seja, as imagens não são em detalhes e passíveis de serem utilizadas para uma efetiva avaliação cuidadosa do real estado em que os fios de cabelos se encontram. [007] Despite proving functional, it was observed that this solution known in the state of the art continues to present the limitation of not being able to carry out an assessment of the condition, and mainly, of possible damage to the hair strands, this is because the system and Methods disclosed in the prior art propose limited solutions for identifying the general characteristics of the hair, such as whether it is dry, oily, straight, the level of shine, volume, frizz, colors, etc. and, also, in a detached way, that is, the images are not in detail and can be used for an effective careful assessment of the real state of the hair strands.
[008] Assim, como deve ser apreciado por um técnico no assunto, essas soluções conhecidas no estado da técnica apresentam uma proposta que, apesar de serem funcionais para o seu propósito, não seriam capazes de realizar efetivamente uma avaliação detalhada do real estado dos fios de cabelo dos usuários, muito menos identificar e indicar um produto para realizar o tratamento desses fios danificados. [008] Thus, as should be appreciated by a person skilled in the art, These solutions known in the state of the art present a proposal that, despite being functional for their purpose, would not be able to effectively carry out a detailed assessment of the real condition of users' hair strands, much less identify and indicate a product to carry out the treatment of these damaged strands.
[009] Desse modo, verifica-se que os sistemas e métodos conhecidos no estado da técnica apresentam alguns aspectos técnicos, construtivos e funcionais que poderiam ser aperfeiçoados a fim de obter uma solução capaz de realizar a avaliação do estado do fio de cabelo do usuário de forma rápida, eficiente e com custos relativamente reduzidos, mas principalmente que pudessem ser facilmente manipulados, ao ponto de que o próprio usuário ou o vendedor pudesse executá-lo sem exigir elevada expertise. [009] Therefore, it appears that the systems and methods known in the prior art present some technical, constructive and functional aspects that could be improved in order to obtain a solution capable of evaluating the condition of the user's hair. quickly, efficiently and with relatively low costs, but mainly that could be easily manipulated, to the point that the user or the seller themselves could execute it without requiring high expertise.
[0010] Logo esses são, dentre outros, os problemas, objetivos e soluções que se pretende superar e atingir com o desenvolvimento da presente invenção. [0010] Therefore, these are, among others, the problems, objectives and solutions that are intended to be overcome and achieved with the development of the present invention.
