Research on Medical Image Registration Based on QPSO and Powell Algorithm
Tingting Pan, Ji Zhao · 2015
This paper proposed a multi-resolution search optimization algorithm combining QPSO and Powell algorithm,it can solve the Powell algorithm shortcoming effectively. In this paper, the algorithm were used in two-dimensional MRI images registration.The experimental results show that the algorithm can effectively overcome the problem of local extremum of mutual information function, and improve the precision and speed of registration.
