Time Parallel Denoising Algorithm Based on P-M Equation for Real Image

This paper combines the regularized Perona and Malik model with the time parareal algorithm to denoise the real image which has the characteristics of typical Gaussian noise. This method can remove the noise stably and effectively and has high calculation efficiency. For the real color image of 6000...

Description
Summary:This paper combines the regularized Perona and Malik model with the time parareal algorithm to denoise the real image which has the characteristics of typical Gaussian noise. This method can remove the noise stably and effectively and has high calculation efficiency. For the real color image of 6000×4000 pixels, the time cost can be shortened from one minute in serial computing to a few seconds based on our combination method if we do not care about the requirement of computing hardware. This provides some reference for practical engineering application.
