A process-grammar for shape
M Leyton - Artificial Intelligence, 1988 - Elsevier
Inference rules are developed by which process-history can be recovered from natural
shapes such as tumors, clouds, and embryos, etc. We argue that the inference of history …

Using partial derivatives of 3D images to extract typical surface features
O Monga, S Benayoun - Computer vision and image understanding, 1995 - Elsevier
Three-dimensional edge detection in voxel images is used to locate points corresponding to
surfaces of 3D structures. The next stage is to characterize the local geometry of these …
