基于小波变换的图像压缩编码方法需要知道小波变换后各子带图像的概率密度函数的形状参数,以便设计出最佳的量化器。在本文中,通过KS(Kolmogorov—Smirnov)检验的方法给出了遥感影像小波变换后各子带图像的形状参数,为遥感影像利用小波变换进行压缩提供了设计量化器的依据。
The image compression coding method based on wavelet transform needs to know the shape parameters of the probability density function of each sub-band image after wavelet transform in order to design the best quantizer. In this paper, the shape parameters of each sub-band image after wavelet transform of remote sensing image are given by KS (Kolmogorov-Smirnov) test, which provides the basis for designing the quantizer for remote sensing image to be compressed by wavelet transform.
