Abstract:

Non-rigid image registration is a hot topic of image registration in mathematical morphology, and its parallelism is an important problem. This paper   starts with a mathematical model of non-rigid image registration in topography, followed by its formal definition. Then some new serial non-rigid image  registration algorithms proposed in recent years are classified and analyzed,based on which the related parallel strategies are emphasized in detail. Then we analyze some issues, which should be considered when designing parallel non-rigid image registration algorithms, and give an evaluation of the exi sting parallel algorithms, and draw some conclusions. Finally we point out the problems and challenges of future research.

Key words: non rigid image registration, area based registration, parallel strategy, speedup
