研究了一个特定的9-7小波. 证明了Z97有很好的数学性质,它的提升系数适合ASIC实现. 实验证明了Z97在压缩性能超过CDF97而计算复杂度大大低于CDF97.因此,Z97是基于小波的图像和视频压缩技术首选小波.
We study a particular 9-7 wavelet, and prove that Z97 has good mathematical properties and its lifting coefficient is suitable for ASIC implementation.Experiments show that Z97 has much lower computational complexity than CDF97 when its compressibility exceeds CDF97. Therefore, Z97 is Wavelet-based image and video compression technology preferred wavelet.
