An Improved Bayesian Wavelet Shrinkage Denoising
Yi Zhang · Techniques of Automation and Applications · 2012
In this paper,the key wavelet threshold shrinkage denoising method is researched based on studying wavelet analysis theory deeply.At first,bayesian shrinkage threshold is gotten by bayesian estimation theory based on analyzing distribution feature of wavelet coefficients.Then a novel algorithm of bayesian adaptive shrinkage thresh-old denoising is improved based on space adaptive threshold and edge detection method.The good simulation results are gotten at last.
