Multiresolution elastic matching
WebThe matching process is 3-dimensional without any preference given to the slicing plane. After global alignment the brain atlas is deformed like a piece of rubber, without … WebA multiscale algorithm for elastic (or molded) alignment of images is developed and preliminary results of this molding technique on a variety of images are presented. We have developed a multiscale algorithm for elastic (or molded) alignment of images. There is a wide array of medical applications of elastic (as opposed to strictly rigid) alignment: …

Web1 sept. 2007 · A multi-objective function is used to reflect the similarity between two graphs. The experiments designed to evaluate the algorithm have shown very promising results. It is highly accurate in matching graphs with dissimilarities in shape, number of nodes and degrees of rotation. References Auwatanamongkol, 2000. WebSemi-Automatic Anatomical Tree Matching for Landmark-Based Elastic Registration of Liver Volumes. One promising approach to register liver volume acquisitions is based on the branching points of the vessel trees as anatomical landmarks inherently available in the liver. Automated tree matching algorithms were proposed to automatically find pair ...
