Threshold Based on Wavelet Image De-noising and Refining Processing Tomography
Jianwen Wang · Microelectronics & Computer · 2010
In order to improve the status of white Gaussian noise of computed tomography images(CT images)in the imaging process,it directed an improved wavelet-shrinkage threshold denoising methods with good time-frequency localization and multi-resolution analysis capability.It's able to overcome the man-made shocks caused by singular points in the neighborhood while denoising signal reconstruction in a the traditional wavelet threshold,provide more abundant details of medical diagnosis,better edge information and better visual images.
