Denoising Method of X-ray Digital image based on Multiscale wavelet-change
Xiang Heng Xiao · Microcomputer Information · 2009
According to X -ray digital image’s characteristic, a new method of denoising X -ray digital image was presented. This method based on the different transformation of wavelet transform modulus maxima (WTMM) multiscale edge detetion and using wavelet package denoising method. Simulation results show that higher peak-signal-to-noise (PSNR) ratio and keep the edge information effectively. It can meet the request of the subsequent X-ray digital image process better.
