H.264/AVC is a merging popular video coding standard which have new features. A H.264 open source, X264 code set, adopt motion estimation which consists of diamond search, hexagonal search, uneven multi-hexagon search, exhaustive search and hadamard exhaustive search. According to statistic values, the time-consuming of ME operations during HDTV(1920x1080p) encoding is about 60-80 percent within whole...
Targeted for highly sophisticated visual signal processing, we introduce in this paper complexity metrics or measures of algorithms which featuring architectural information are feedback or back annotated in early design stages to facilitate concurrent exploration of both algorithmic and architectural optimizations. With application to 3D spatio-temporal motion estimation for video coding, we have...
In this correspondence, some image transforms and features such as projections along linear patterns, convex hull approximations, Hough transform for line detection, diameter, moments, and principal components will be considered. Specifically, we present algorithms for computing these features which are suitable for implementation in image analysis pipeline architectures. In particular, random access...
