Abstract

detecção de marca d<39>água utilizando uma mapa de propagação. um método para detectar e selecionar impressão de marca d<39>água em codificação de vídeo é fornecido que compreende acessar uma lista de possíveis marca d<39>água: gerar mapas de propagação de modificações para o vídeo que seriam causados por aplicar as marcas d<39>água respectivas; gerar uma região de detecção responsiva a cada mapa de propagação respectivo que inclui blocos no mapa de propagação que coletivamente classificam mais elevado com relação a um critério de detecção selecionado comparado com cada outra região no mapa de propagação; selecionar uma métrica delimite para avaliar regiões de detecção; e remover marcas d<39>água a partir da lista responsiva a uma comparação de suas regiões de detecção com a métrica de limite.
