Matrix transpose on meshes: theory and practice
Proceedings 11th International Parallel Processing Symposium, 2002 We consider the problem of matrix transpose on mesh-connected processor networks. On the theoretical side, we present the first optimal algorithm for matrix transpose on two-dimensional meshes. Then we consider issues on implementations, show that the theoretical best bound cannot be achieved and present an alternative approach that really ...

Active mesh coding and rate-distortion theory [PDF]
Proceedings of 3rd IEEE International Conference on Image Processing, 2002 This paper presents a video coding scheme for very low bit rate applications. The coding approach relies on active meshes and can be viewed as a particular case of region-based coding. The active mesh is used to efficiently represent and code the various regions of the scene and the motion information.
