【Abstract】 This paper has outlined the theory of wavelet threshold denoising , then done comparing experiments using several good threshold denoising methods. Finally according to the theory analysis and simulation results, the paper discusses several kinds of factors which affect the denosing capability in a complete denoising algorithm. That provides the date reference of threshold denoising methods in actual image process.更多还原
