Abstract

a presente invenção refere-se a um método para automação de teste de resolução em imagens digitais que compreende: prover uma imagem digital com pelo menos uma estrutura que deve ser discernida na imagem; extrair características dos dados da imagem digital, as referidas características incluindo características relacionadas à pelo menos uma estrutura que deve ser discernida; e classificar a pelo menos estrutura como resolvida ou não resolvida através de um algoritmo de aprendizagem de máquina, em que o algoritmo foi treinado com base em preditores de resolubilidade que incluem características extraídas de uma base de dados de imagem de estruturas previamente obtidos e dados de classificação dessas estruturas como resolvida ou não resolvida, sendo tal classificação realizada por pelo menos um operador humano.the present invention relates to a method for automating resolution testing on digital images which comprises: providing a digital image with at least one structure that must be discerned in the image; extract characteristics from the digital image data, said characteristics including characteristics related to at least one structure that must be discerned; and classify the at least structure as resolved or not resolved through a machine learning algorithm, in which the algorithm was trained based on resolvability predictors that include characteristics extracted from a previously obtained structures image database and data from classification of these structures as resolved or not resolved, such classification being performed by at least one human operator.
