| Abstract: | Geometric operations are basic operations in computer graphics and computer vision. How to imple- ment the operations effectively with high speed, sometimes often in real time, is a major problem in modem media applications. A data parallel implementation of geometric operations is proposed and conclusions are proved in this paper. It shows that the computation complexity of data parallel implementation scheme presen- ted in this paper is O（ M ＋ N）. It can be used to improve the efficiency of geometric operations and can easily meet the real time requirements of the digital image processing. |
