Quantization of adaptive 2D wavelet decompositions
Classical linear wavelet representations of images have the drawback that they are not well-suited to represent edge information. To overcome this problem, nonlinear multiresoluti...

Adaptive image segmentation based on color and texture
We propose an image segmentation algorithm that is based on spatially adaptive color and texture features. The features are first developed independently, and then combined to obt...

Optimal Prefix Codes for Some Families of Two-Dimensional Geometric Distributions
Lossless compression is studied for pairs of independent integer-valued symbols emitted by a source with a geometric probability distribution of parameter q (0, 1). Optimal prefix...

On-Line Adaptation in Image Coding with a 2-D Tarp Filter
On-line adaptation to nonstationary distributions is essential to good performance in image coding. Fixed-size contexts (with adaptive tables) are also widely used, in conjunction...

Multi-modal speaker diarization of real-world meetings using compressed-domain video features
Speaker diarization is originally defined as the task of determining “who spoke when” given an audio track and no other prior knowledge of any kind. The following article sho...
