Research of Image Denoising Based on Wavelet Threshold
This paper introduces the denoising theory based on wavelet threshold ,and it presents a new threshold function based on traditional soft and hard threshold function and weighted threshold function。Simulation results show that：the new threshold function can be more effective to eliminate noise and restore image.
