# Random Walk Graph Laplacian based Smoothness Prior for Soft Decoding of JPEG Images

7 Jul 2016Xianming LiuGene CheungXiaolin WuDebin Zhao

Given the prevalence of JPEG compressed images, optimizing image reconstruction from the compressed format remains an important problem. Instead of simply reconstructing a pixel block from the centers of indexed DCT coefficient quantization bins (hard decoding), soft decoding reconstructs a block by selecting appropriate coefficient values within the indexed bins with the help of signal priors...
