Abstract:
In this study, we propose three extended fitting methods to the
standard ASM(activeshape model), Firstly, profiles are extended from 10 to 20;
Secondly, profiles of different landmarks are constructed individually; Thirdly,
length of the profiles is determined adaptively with the change of level during
searching, and the displacements in the last level are constrained, Each method
and the combination of three methods are tested on the SlTU(Shanghai Jiaotong
University) face database. In all cases, compared to the standard ASM, each
method improves the accuracy or speed in a way, and the combination of three
methods improves the accuracy and speed greatly.
