In this paper, a digital image watermarking technique based on Discrete Wavelet Transform (DWT) will be proposed. This scheme is designed utilizing principles deriving from the hu...
We investigate the task of compressing an image by using different probability models for compressing different regions of the image. In an earlier paper, we introduced a class of...
Abstract. The Burrows-Wheeler transform (BWT) and block sorting compression are closely related to the context trees of PPM. The usual approach of treating BWT as merely a permutat...
