KPN Research has developed an all-purpose check recognition system for the Dutch Postbank. This Image Recognition and Interpretation System (IRIS) is the result of more than thirt...
As a key part of universal source coding, context quantization is very important for improving compression performance. However, in most existing methods, the quantizer is trained...
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, an anisotropic total variation (ATV) minimization is combined with the new adaptive tetrolet transform for discontinuity-preserving image processing. In order to su...
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...
