小波阈值降噪的matlab代码 里面有两个程序 一个比较了软硬阈值去噪 另外一个对多层小波分解的阈值去噪做了对比-Wavelet threshold denoising matlab code there are two programs a relatively soft and hard thresholding is another multi-layer wavelet threshold denoising to do a comparison

mage compression is one of the most important step in image transmission and storage. Most of the state-of-art image compression techniques are spatial based. In this code, a histogram based image compression technique is implemented based on multi-l
