A method of automated landmark generation for automated 3D PDM construction
2000
Image and Vision Computing
Preserved Fulltext
A previous publication has described a method of pairwise 3D surface correspondence for the automated generation of landmarks on a set of examples from a class of shape [3] . ...
We show how the pairwise corresponder can be used in a extension of an existing framework for establishing dense correspondences between a set of training examples [4] to build a 3D Point Distribution ...
Such a tree provides a framework for the automated landmarking of the input example shapes necessary for the production of a 3D PDM. ...
