摘要

In this paper, we shall propose an image refining method that incorporates the digital watermarking technique and Vector Quantization to recover an image after transmission on a network unclean or tampered by people. In our method, we embed the codevector indices of the original image into the original image itself via the watermarking technique. Then, in the refining phase, the indices are retrieved and employed to detect and recover the supposedly partially damaged image block. The experimental results show that the performance of our method is excellent in suppressing block noise.
