Parallel image registration with OpenMP and MPI
Proceedings - 2009 International Conference on Computational Intelligence and Software Engineering, CiSE 2009(2009)
Abstract
As the image size increases, most numerical approaches for image registration based on the pixel matrices computation will cost a large executing time, then one of the most efficient solving methods is parallel computing. In this paper, we discuss two parallel implementation methods to perform the PDE-based image registration computing. One is the multithreading process with OpenMP on a dual core computer, another is the data-block and multithreads processing with MPI and OpenMP on a 4 nodes cluster disposed by WCCS. Some experimental results show that these two methods can produce the large size image registration and reduce the computation complexity. ©2009 IEEE.
