Journal ArticleDOI
A modified fuzzy c-means algorithm for bias field estimation and segmentation of MRI data
TL;DR: A novel algorithm for fuzzy segmentation of magnetic resonance imaging (MRI) data and estimation of intensity inhomogeneities using fuzzy logic and the neighborhood effect acts as a regularizer and biases the solution toward piecewise-homogeneous labelings.
Journal ArticleDOI
Surface signatures: an orientation independent free-form surface representation scheme for the purpose of objects registration and matching
Sameh M. Yamany,Aly A. Farag +1 more
TL;DR: It is shown that the signature representation can be used to recover scaling transformation as well as matching objects in 3D scenes in the presence of clutter and occlusion.
Proceedings ArticleDOI
A system for human jaw modeling using intra-oral images
Sameh M. Yamany,Aly A. Farag +1 more
TL;DR: The overall purpose of this research is to develop a model-based vision system for orthodontics that will replace traditional approaches and can be used in diagnosis, treatment planning, surgical simulation and implant purposes.

System and method for 3-D digital reconstruction of an oral cavity from a sequence of 2-D images
TL;DR: In this paper, an integrated computer vision system that constructs a 3D model of the patient's dental occlusion using an intra-oral video camera is presented, where a modified shape from shading technique, using perspective projection and camera calibration, extracts the 3D information from a sequence of two-dimensional images of the jaw.
Journal ArticleDOI
A new genetic-based technique for matching 3-D curves and surfaces☆
TL;DR: Registration using the GCP/GA technique is found to be signiicantly faster and of comparable accuracy than two popular techniques in the computer vision and medical imaging literature.
