PC based real-time implementation for regiond matching in stereo vision
Ding Jiang-lin · Journal of Zhejiang University(Sciences Edition) · 2003
The requirement of mass computation power was one of the main obstacles to the applications based on stereo matching. This paper tried to solve this problem in two ways. First, the computation redundancies were reduced using the box-filtering technique. Then further optimizations related to memory organization and cache efficiency, Streaming SIMD Instructions, and the parallel process using Hyper-threading technology have been efficiently implemented on Intel Pentium 4 based computer. The test result proves that the approach proposed in this paper can reduce the process time effectively.
