Abstract

"MéTODO E SISTEMA PARA EFETUAR A DETECçãO DE EVENTOS E RASTREAMENTO DE OBJETOS EM FLUXOS DE IMAGENS". Método de e sistema para efetuar a detecção de eventos e rastreamento de objetos em seq³ências de imagem instalando no campo, uma série de dispositivos de captura de imagem, onde cada dispositivo inclui um processador programável local para converter a seq³ência de imagem captada que consiste de uma ou mais imagens, em um formato digital, e um codificador local para gerar características a partir da seq³ência de imagens. Estas características são parâmetros que estão relacionados com atributos de objetos na seq³ência de imagens. O codificador também transmite um fluxo de características sempre que as características de movimento excederem um correspondente valor limiar. Cada dispositivo de captura de imagem é conectado com uma rede de dados através de um correspondente canal de comunicação de dados. Um servidor de processamento de imagem que determina o valor limiar e processa o fluxo de características é também conectado com a rede de dados. Sempre que o servidor recebe características de um codificador local através de seu correspondente canal de comunicação de dados, o servidor fornece indicações relativas a eventos nas seq³ências de imagens processando o fluxo de características e transmitir estas indicações para um operador.
