The research of wavelet adaptive threshold gray scale image denoising

Abstract

The characteristics of two traditional wavelet compromise methods, referred to as the soft-thresholding method and the hard thresholding method, were analyzed in the wavelet domain. A new compromise thresholding method that improves peak-signal-to-noise ratio (PSNR) of denoising is presented, based on the standard compromise threshold method, yet more… (More)
