On the Existence of Optimal Exact-Repair MDS Codes for Distributed Storage
The high repair cost of (n, k) Maximum Distance Separable (MDS) erasure codes has recently motivated a new class of codes, called Regenerating Codes, that optimally trade off stor...

Data pruning-based compression using high order edge-directed interpolation
This paper proposes a data pruning-based compression scheme to improve the rate-distortion relation of compressed images and video sequences. The original frames are pruned to a s...

Quantizers with Uniform Encoders and Channel Optimized Decoders
Scalar quantizers with uniform encoders and channel optimized decoders are studied for uniform sources and binary symmetric channels. It is shown that the Natural Binary Code and ...

Color Palette Images Re-indexing by Self Organizing Motor Maps
Palette re-ordering is a well known and very effective approach for improving the compression of color-indexed images. If the spatial distribution of the indexes in the image is s...
