Many practical applications generate irregular, nonbalanced divide-and-conquer trees which have different depths, possibly also different numbers of successors at different levels...
Abstract. In considering a problem in access control for scalable multimedia formats, we have developed new methods for constructing a key assignment scheme. Our first contribution...
ct A very fast, low complexity algorithm for resolution scalable and random access decoding is presented. The algorithm is based on AGP (Alphabet and Group Partitioning) [1], where...
This paper develops a new mask in the spatial domain for image watermarking. The mask exploits the properties of human visual system with respect to background luminance, the edge...
good data partitioning scheme is the need of the time. However it is very diflcult to arrive at a good solution as the number of possible dutupartitionsfor a given real lifeprogra...
