| Abstract: | Based on the profound analysis on wavelet threshold image denoising, several classical wavelet denoising methods ate introduced in detail. For images of wavelet decomposition and reconstruction, detailing its decomposition steps and algo- rithms to analyze the problem of wavelet decomposition process of selecting the number of layers and wavelet reconstructed image and gives some selected basis.The principles and the algorithm of the relativity of the wavelet coefficient denoising method are introduced .Some key problem on denoising method based on wavelet threshold are discussed in detail. |
