Paperback. O livro apresenta uma tecnica de compressao de video baseada na quantizacao vetorial, que consegue a compressao atraves da eliminacao da redundancia espacial. A compressao de um ficheiro de video consiste na eliminacao das redundancias e dos elementos irrelevantes existentes entre os fotogramas do video. Essas redundancias sao de natureza temporal e espacial. A redundancia temporal e eliminada atraves da utilizacao da tecnica de estimativa de movimento. Alem disso, os padroes MPEG-2 e MPEG-4 utilizam a estrategia ME. A redundancia espacial e reduzida atraves do metodo VQ. A tecnica mais recente pertence a categoria da compressao de video baseada em VQ. Geralmente, a VQ envolve a concecao de um livro de codigos melhor, uma vez que a taxa de compressao depende disso. As tecnicas de VQ dividem-se em duas categorias principais: concecao eficiente do livro de codigos e geracao rapida do livro de codigos. O algoritmo VQ mais conhecido e o LBG, que e utilizado para gerar o livro de codigos, mas pode ficar preso em otimos locais, o que degrada a qualidade do video apos a descodificacao. As tecnicas heuristicas sao mais adequadas para alcancar o otimo global, mas necessitam de uma solucao inicial e exigem um tempo de computacao elevado. This item is printed on demand. Shipping may be from multiple locations in the US or from the UK, depending on stock availability.…
