wavelet transform and fast wavelet transformIn general, image compression reduces the number bits required to represent an image. The main significance of image compression is that the quality of the image is preserved. This in turn increases the storage space and thereby the volume of the data ...
因为它们本身固有的多尺度性质,小波编码方法很适合那些重视可伸缩 性(scalability)和可容忍退化(tolerabledegradation)的应用。基于小波变换的图像压缩有着非常优越的特点。即压缩比 高、压缩速度快,压缩后能保持信号与图像的特征基本不变,且在传递过程中可以抗干扰等等。基于小波变换的图像压缩是在二维离散小波变换的基础...

As such, the 9×7 kernel has four vanishing moments per wavelet filter. Moreover, this kernel is nearly orthogonal and has a higher factorization-order that the 5×3 kernel. As such, it also offers an improved energy compaction performance for lossy compression compared to the 5×3 kernel....
