Yuhong Liu · Computer Engineering and Applications Journal · 2007
This paper presents a wavelet shrinkage algorithm for image denoising based on two-local threshold.This algorithm presents two-local threshold based on the wavelet coefficients'magnitude,spatial regularity,and the segment of the denoised image.Shrinking and reconstructing the wavelet coefficients using the two-local threshold,and we can get a high quality image.The algorithm has some advantages such as low complexity,fast speed computation,high quality image denoising.The performance of the method is an improvement upon some other methods in the literature.
