摘要
本文研究了彩色图像的压缩编码在分级传输中的应用．选择双正交小波，对彩色图介的Y、I和Q分量分别进行小波分解．然后根据变换域的数据特性并结合视觉系统（HVS）特性．提出了一种合适的压缩编码方案，并给出了图像分级传输的效果．实验结果表明，这种压缩编码适用于图像的分级传输．
In this paper, color image coding in propressive transmission is investigated . The components Y, Iand Q in the color image are respectively decomposed using the bio-orthogonal wavelet . Combining the proper ties of the data in the transformed field and the Human vision System the coding method is presented, and theeffect of progressive transmission is displayed. The experiment shows this is an ideal imge coding scheme in progressive transmission .
