Spatial Join Selectivity Using Power Laws
We discovered a surprising law governing the spatial join selectivity across two sets of points. An example of such a spatial join is "find the libraries that are within 10 m...

Fast H.264/MPEG-4 AVC Transcoding Using Power-Spectrum Based Rate-Distortion Optimization
Since variable block-size motion compensation (MC) and rate-distortion optimization (RDO) techniques are adopted in H.264/MPEG-4 AVC, modes and motion vectors (MVs) in input stream...
