Abstract:

On the basis of the classical algorithm of the image denoising based on total variation, a numerical algorithm of total variation based on adaptive fidelity term was proposed. Different intensities of denoising were used to avoid the shortages of the traditional method and then numerical method was chosen so as to realize our algorithm. On the premise of the classical total variation, our method made up for the shortcomings of the original ladder and excessive smoothing effect, especially for the image denoising of fine texture and detail images, it made the remain of most of their image characteristics. Our
 treatment can be applied to a series of image processing based on partial differential equations simply.
