1.
Choosing proper orthogonal wavelet function,the low frequency sub-band was enhanced obviously and the high frequency sub-band was restrained moderately to realize image enhancing via the modulation of information entropy window.
采用信息熵窗小波低频子带分析的方法,目的是对缺乏足够能量的低照度和低对比度图像进行增强。
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。
3) low frequency and narrow bandwidth
