Abstract
"MéTODO E APARELHO PARA DETECTAR QUADROS DE CARACTERE USADOS EM PROCESSOS DE VOTAçãO". Em um método de detecção de quadro de caractere, pixéis de extremidade nas extremidades de linhas de quadros de caractere são extraídos de pixéis de cinza de uma imagem de pixel de cinza. Então os gradientes de cinza <sym>(i, j) são calculados nos pixéis de extremidade. Então, regiões de votação (1201, 1202, 1203, 1204) com respeito aos pixéis de extremidade são estabelecidas de acordo com os gradientes de cinza dos mesmos. Então, processos de votação são executados incrementando contagens de votação em coordenadas dentro das regiões de votação. Finalmente, as coordenadas de pico (PP(i, j) com contagens de votação de pico são detectadas a partir das coordenadas de modo que as coordenadas de pico sejam determinadas para serem centros dos quadros de caractere.
