摘　　要：针对彩色图像的特性,对零树算法在具体算法中的应用进行了改进,得出一种新的算法———不完全扫描法,并将该算法应用到彩色图像压缩中.首先将彩色图像从RGB空间变换到亮度、色度YUV空间进行压缩编/解码.通过理论分析和仿真实验表明:在保证恢复图像质量的前提下,提高了压缩比和编/解码速度.In view of color image characteristic, the paper improves the zero algorithm in the application of concrete algorithm, draws a new algorithm-incomplete scanning method, which is applied to color image compression. The authorsconvert color image from the RGB space into luminance-chrominance YUV space, then compress the converted image to encode/decode. Theoretical analysis and simulation experiment indicate that the compression ratio and encoding/decoding speed are increased, at the sase time the quality of restored image is guaranteed.
