Abstract

codificação de vídeo usando detecção compressiva. trata-se de métodos e aparelhos que são proporcionados para codificadores de vídeo usando detecção compressiva. o método de codificação codifica um bloco de imagem em uma imagem mediante a geração de um vetor de medição para o bloco de imagem, a codificação do vetor de medição e a reconstrução do bloco de imagem por meio da minimização de uma dispersão de sinal do bloco de imagem em resposta ao vetor de medição codificado, o vetor de medição incluindo coeficiente de transformada relacionados ao bloco de imagem (900). um método de decodificação correspondente decodifica um bloco de imagem em uma imagem medianate o recebimento de um vetor de medição e a reconstrução do bloco de imagem, a decodificação do vetor de medição e a reconstrução do bloco de imagem mediante a minimização de uma dispersão de sinal do bloco de imagem em resposta ao vetor de medição codificado, em que o vetor de medição inclui coeficientes dde transformada relacionados ao bloco.
