Dynamic Scene Occlusion Culling Using a Regular Grid
We present an output-sensitive occlusion culling algorithm for densely occluded dynamic scenes where both the viewpoint and objects move arbitrarily. Our method works on a regular ...

Vector Bank Based Multimedia Codec System-on-a-Chip (SoC) Design
—In this paper, we present a design architecture of implementing a ”Vector Bank” into video encoder system, namely, an H.264 encoder, in order to detect and analyze the movin...

On Two Forms of Structural Recursion
We investigate and compare two forms of recursion on sets for querying nested collections. The rst one is called sri and it corresponds to sequential processing of data. The second...
