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...
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...
The paper proposes a novel algorithm to enhance the quality of H.264/AVC compressed video sequences by using an inloop spatio-temporal motion compensated lter (MCSTF). Extra infor...
We describe a scalable and general-purpose framework for auto-tuning compiler-generated code. We combine Active Harmony’s parallel search backend with the CHiLL compiler transfo...

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...
