This paper describes the development of a layered structure of a multi-resolutional scalable video codec based on the Color Set Partitioning in Hierarchical Trees (CSPIHT) scheme....
Since most real-world applications of classification learning involve continuous-valued attributes, properly addressing the discretization process is an important problem. This pa...
A set of n points in the plane is a universal pointset for a given class of graphs, if any n-vertex graph in that class can be embedded in the plane so that vertices are mapped to...
