摘要 提出一种层式余弦变换的零树图像编码方法 (EZLDCT)。与EZDCT相比 ,能较好地消除方块效应 ,且对复杂的图像在相同压缩比的情况下有更高的PSNR值。 An algorithm,namely the embedded zerotree for layered DCT(EZLDCT) is proposed in this paper Compared with EZDCT,it can reduce blocking artifacts efficiently and gain better image quality for complex images at the same compression ratio
