Water Level Detection for Functionally Layered Video Coding
This paper proposes a new type of layered video coding especially for the use of monitoring a river or a water channel. A sensor node of the system decomposes a video signal into ...

Analysis of absorbing sets and fully absorbing sets of array-based LDPC codes
The class of low-density parity-check (LDPC) codes is attractive, since such codes can be decoded using practical message-passing algorithms, and their performance is known to app...

Multichannel Image Compression by Bijection Mappings onto Zero-Trees
A new approach to multichannel image compression is introduced where the intra- and cross-band correlations are jointly exploited in a surprisingly simple yet very effective manner...

Texture compression of light maps using smooth profile functions
Light maps have long been a popular technique for visually rich real-time rendering in games. They typically contain smooth color gradients which current low bit rate texture comp...

Image Warping using Adaptive Partial Matching
The block-matching motion estimation algorithm using a translational motion model cannot provide acceptable image quality in low bit-rate coding. To improve coding performance, we ...
