Image Semi-soft Threshold Denoising Method Based on Improved Ridgelet Transform
|
Abstract:
Ridgelet is a multi-scale geometric analysis method that comes from wavelet and is better than it,which is a-pplied in the image processing.This paper presented a new denoising way using the essence of wavelet image denoising,the new one is based on adaptive threshold of Bayesian estimation and semi-soft threshold techniques.In view of little scratch caused by ridgelet transform,the interference was eliminated with the method of shift invariant.The experimental results show that this method can better deal ...
