A Time Dependent Model via Non-Local Operator for Image Restoration

Conference paper
Part of the Advances in Intelligent Systems and Computing book series (AISC, volume 214)


Image is ubiquitous in modern communication. However, during the process like image acquisition and transmission, blur will appear on the reproduced image. This paper presents a time dependent model for image restoration based on the non-local total variation (TV) operator, which is robust to the noise and makes full use of the spatial information distributed in the different image regions. Experiment results demonstrate that the proposed model produces results superior to some existing models in both visual image quality and quantitative measures.
