Image deblocking is a postprocessing method that aims to suppress the compression artifacts without changing existing JPEG coding standard. We propose an image deblocking method, which is based on deep convolutional neural networks. The proposed method takes full advantage of the characteristics of wavelet domain and pixel domain to restore the high-frequency information of compressed images and maintain low-frequency information, respectively. In addition, a fusion layer is employed to fuse the merits of two domains. Extensive experiments demonstrate that the proposed method outperforms the state-of-the-art deblocking methods in both subjective vision and objective evaluation.
