On Doubly-Cyclic Convolutional Codes
Cyclicity of a convolutional code (CC) is relying on a nontrivial automorphism of the algebra F[x]/(xn - 1), where F is a finite field. A particular choice of the data leads to th...

Rate-Distortion Optimized Region-Based Video Coder
In this paper, we present an efficient region-based video coding scheme. The region partioning is optimized according to a rate-distortion criterion in order to achieve constant b...

Trellis-Based R-D Optimal Quantization in H.263+
Abstract—We describe a trellis-based algorithm which enables R-D optimum quantization decisions in the H.263+ video coding standard. The algorithm allows the quantization decisio...
