This paper introduces a VHDL realization of a new efficient intra prediction scheme that aims to enhance the compression efficiency of the H.264 standard. The new proposed algorithm is called Best Prediction Matrix Mode (BPMM). The main idea behind the new prediction scheme is to combine the most usable intra prediction modes, {vertical horizontal DC}, into(More)

The most crucial question when using a cryptographic scheme is how to select the cryptographic parameters such that the scheme is "secure" and reasonably efficient at the same time. In this article that question will be considered for cryptographic schemes based on class groups of imaginary quadratic number fields. Specifically, an algorithm is investigated(More)
