Abstract:

The authors constructed wavelet transformation matrix to process images in view of Mallat algorithm, in order to solve the questions that FRIT can only apply to pixelsize image of prime number, generated random signal and “around” phenomenon in image processing, and proposed three kinds of improved FRIT methods that were combined with boundary prolong methods, which were used in the image denoising, the experiment showed that the denoising performance of the image with a straight line feature is better.
