In this paper, a comparative study of lossless compression algorithms is presented. The following algorithms are considered: UNIX compress, gzip, LZW, CCITT Group 3 and Group 4, J...
Application areas such as medical imaging or satellite imaging often store large collections of similar images. Lossless compression techniques are ...
We propose a new, very low complexity, single-pass, algorithm for compression of continuous tone compound documents, known as GRAFIT (GuaRAnteed FIT) that can guarantee a minimum ...
This paper presents a VLSI Architecture to implement the forward and inverse 2-D Discrete Wavelet Transform (FDWT/IDWT), to compress medical images for storage and retrieval. Loss...
This report proposes a new coding method, which realizes lossless, near-lossless and lossy coding with a unified single algorithm. The method is based on a lifting-structured loss...
