Cosine Transform Priors for Enhanced Decoding of Compressed Images
Abstract. Image compression methods such as JPEG use quantisation of discrete cosine transform (DCT) coefficients of image blocks to produce lossy compression. During decoding, an...

A Reversible Watermarking Scheme for JPEG-2000 Compressed Images
In this paper, we present a novel reversible watermarking scheme for image authentication for JPEG/JPEG-2000 coded images. Since the watermarking scheme is reversible, the exact o...
