Information hiding for authenticating and recovery the missing information of the multimedia has been exploited extensively in the last decade. We propose a novel self-recovery watermarking algorithm based on wavelet tansformation and set partitioning in hierarchical trees coding. Utilizing the zero-tree coding to compress each block of the host image and(More)
Non-local means (NLM) is an effective denoising method that explores self-similarities between neighborhoods in the image for noise removal. The traditional NLM method computes pixel similarity using the globally fixed decay parameter and invariable matching window. However, a fixed decay parameter and constant window size for the whole image is difficult(More)
