Abstract: With the popularization of multicore CPU, it will be the trend of CPU and be used to different applications. A multicore-based parallelized differential evolution algorithm is proposed, which takes advantage of parallel computing capabilities of multicore CPU on graphic workstation. It accomplishes the parallel evolution algorithm and realizes the multicore-based parallelized fast medical image registration. The experimental results show that, it not only has no difference in precision and stability with traditional image registration based on differential evolution, but also exhibits fast convergence and almost has an ideal speedup.

Key words: differential evolution, multicore Central Processing Unit（CPU）, parallelization, image registration
