摘要: 本文報道了一種新的活動圖像編碼算法,稱為自適應(yīng)多值量化的亞抽樣塊截斷編碼。模擬結(jié)果表明:這種新算法比現(xiàn)有的其它同類算法有更好的性能,壓縮比為30,信噪比為35.4dB,圖像主觀質(zhì)量良好,在現(xiàn)有個人計算機上可以用軟件實時實現(xiàn)。

Abstract: In this paper, a novel moving picture coding algorithm, called the adaptive multilevel quantized subsampled block truncation coding is presented. The experiments show that this algorithm has better performance than the other algorithms of the same kind and can be realized in real time with software in current PC, the compression ratio is 30 and the peak signal to noise ratio is 35.4 dB. -
