Markers localization of 3D face based on curvature and geometric constraints
Jie Tao · Microcomputer Information · 2009
A method of markers localization of 3D face based on Shape Index features and geometric constraints was proposed in this paper.Firstly,the continuous Shape Index features of model were computed after surface fitting,segmentation and region label was done with these Shape Index features,then the regions were selected by geometry constrained model,finally,the markers were ob-tained.Experiment shows our method is robust and its average accuracy higher than 90%.
