2.
By analysis on coefficient characteristic after discrete wavelet transform,multiple description coding method based on discrete wavelet transform is proposed,the method generates multiple description bit-stream by restructuring and assigning wavelet coefficients of low frequency sub-band after discrete wavelet transform.
在分析离散小波变换后系数特性的基础上,提出了一种基于离散小波变换的多描述编码方法,它通过将离散小波变换后的低频子带的小波系数进行重组赋值产生多描述码流。
2) low frequency sub-band image
低频子带图像
