Notes:
Digital image correlation (DIC) is a whole-field and non-contact strainmeasuring method. It could provide deformation information of a specimen byprocessing two digital images that are captured before and after the deformation. Inthis work, a hybrid genetic algorithm, in which a simulated annealing mutationprocess and adaptive mechanisms are added to the real-parameter genetic algorithm,is used to search the corresponding subset after deformation. To invest the accuracyand reliability of this method, some key parameters are considered. The resultsindicate that the out-of-plane shift should be included, and a subset with 30x30 pixelsshould be recommended. The population size of 500, 100 generations, and 60iterations are good enough. As for the searching strategy, it is recommended that thedesign variables are divided into three groups, each time only one group is undersearch, and they takes terms consecutively
