—A symmetrical second-generation wavelet named zzxb7.9 with two vanishing moments was constructed according to the lifting scheme introduced by Sweldens and used to the image compression. The experimental results show that the second-generation wavelet zzxb7.9 is to be promising in image compression because of its better quality video than that produced by(More)
A symmetrical second-generation wavelet named zzxb7.9 with two vanishing moments was constructed according to the lifting scheme introduced by Sweldens etc. and used for image denoising. Simulated noise images are used to evaluate the denoising performance of the second-generation wavelet zzxb7.9. The experimental results show that the second-generation(More)
