Abstract
"PROCESSO DE RECONHECIMENTO DE CARACTERES E FORMAS". Patente de Invenção compreendido por um método de binarização/segmentação, no qual a imagem é dividida em pequenos quadrados, calculando para um deles o contraste, sendo a mesma realizada a partir dos quadrados que apresentarem maior contraste e somente ao longo da borda, à medida que a mesma é detectada, tendo como limite geralmente a capacidade de processamento do equipamento, um processo de comparação de cores (RGB), através da distância entre as mesmas quando representadas no espaço delimitado por um cubo. Compreende ainda, um método de representação e comparação e recuperação de formas, utilizando-se somente segmentos de reta formando entre si ângulo de 90<198>, bem como, maneira de armazenar e recuperar informações que permitam representar e comparar polígonos."RECOGNITION PROCESS OF CHARACTERS AND FORMS". Patent of Invention comprised of a binarization / segmentation method, in which the image is divided into small squares, calculating the contrast for one of them, and it is made from the squares with the highest contrast and only along the edge as that it is detected, having as a limit generally the processing capacity of the equipment, a process of color comparison (RGB), through the distance between them when represented in the space delimited by a cube. It also comprises a method of representation and comparison and shape retrieval, using only straight line segments forming a 90 <198> angle, as well as a way to store and retrieve information to represent and compare polygons.
