This paper introduces two-dimensional (2D) hierarchical, content-based mesh modeling and compression for interactive digital video processing. The hierarchical nature of the mesh model enables diierent users to employ diierent meshes of varying level of detail to represent the same content depending on the computational resources and channel bandwidth that are available. In particular , a new m...

This paper discusses the dimensions of the spline spaces over T-meshes with lower degree. Two new concepts are proposed: extension of T-meshes and spline spaces with homogeneous boundary conditions. In the dimension analysis, the key strategy is linear space embedding with the operator of mixed partial derivative. The dimension of the original space equals the difference between the dimension o...

This paper compares the performance of hierarchical ring-and mesh-connected wormhole routed shared memory multiprocessor networks in a simulation study. Hierarchical rings are interesting alternatives to meshes since i) they can be clocked at faster rates, ii) they can have wider data paths and hence shorter message sizes, iii) they allow addition and removal of processing nodes at arbitrary lo...

Two-dimensional mesh-based models provide a good alternative to motion estimation and compensation. The estimation of the best node-point motion vectors is a challenging task. To this effect, Nakaya and Harashima proposed a hexagonal matching procedure. Toklu et al. improved the hexagonal search algorithm in terms of both motion-estimation accuracy and computational complexity by employing a hi...
