Abstract

"CORREçãO DE DISTORçõES NO PROCESSAMENTO DE FORMULáRIOS". Um método para o processamento de uma imagem de entrada (20) inclui a aplicação de uma ou mais transformações (50) à imagem de entrada, por meio do que deslocamentos diferentes são aplicados a pixels diferentes na imagem de entrada, de modo a se gerar uma imagem de saída (Fig. 3). Uma região (22) contendo um conteúdo (24) de interesse é selecionada na imagem de saída, e a região correspondente à região selecionada na imagem de saída é localizada na imagem de entrada. O conteúdo da região localizada na imagem de entrada é substituído pelo conteúdo da região selecionada na imagem de saída.
