Abstract

"PROCESSOS DE REPRESENTAR UM OBJETO OU UMA PLURALIDADE DE OBJETOS QUE APARECEM EM UMA IMAGEM PARADA OU DE VìDEO E DE PESQUISAR UM OBJETO EM UMA IMAGEM PARADA OU DE VìDEO, APARELHO, PROGRAMA E SISTEMA DE COMPUTADOR E MEIO DE ARMAZENAGEM QUE PODE SER LIDO POR COMPUTADOR". Um processo para apresentar um objeto que aparece em uma imagem processando um sinal que corresponde a uma imagem parada ou de vídeo, que compreende uma etapa de derivar uma apresentação de espaço de escala de curvatura (CSS) do delineamento de um objeto suavizando o delineamento do objeto, uma etapa de derivar no mínimo um parâmetro adicional que reflete a distribuição da forma ou dimensão de uma versão obtida suavizando a curva original, e uma etapa de correlacionar a apresentação CSS com o parâmetro adicional que serve como um descritor de forma do objeto.
