Facial Feature Location Based on Improved ASM
Xi Wen Qin, Hong Yu Zhang, Xiao Gang Dong · Advanced materials research · 2012
It makes a series of improvements of the traditional oriented way of human face, which is based on ASM. First, we orientate some outstanding feature points on the basis of the results of face test, then make use of these feature points to initialize model. Second, we get some statistics information of the edge in the training process and take a vertical range of the edge in a feature point. According to the scope of positioning, we looked at the local search results on its position before reconstruction the local adjust, thus preventing the search results from departing from the feature pointed have orientated.
