As wavelet-based image coding is set to become more widely used (e.g. with the completion of the JPEG2000 standard), memory efficiency for wavelet-based coding is becoming an incr...
The Discrete Wavelet Transform (DWT) forms the core of the JPEG2000 image compression algorithm. Since the JPEG2000 compression application is heavily data-intensive, the overall ...
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 ...
In this paper, a new fast video codec using Wavelet Difference Reduction (WDR) algorithm is presented. This proposed video codec is inspired by the concept of motion JPEG; namely,...
Efficient compression algorithms generally use wavelet transforms. They try to exploit all the signal dependencies that can appear inside and across the different sub-bands of th...
