Learning a coarse-to-fine matching pursuit for fast point search in images or volumetric data using multi-class classification
A landmark location system for locating landmarks in volumes includes a medical image database including volumes of medical images, a learning unit that trains a multi-class classifier to locate a landmark point in each volume from extracted features of the volumes near a sample point offset from the landmark point and discrete displacements of the sample point to the landmark point, and a landmark locator that locates the landmark point in an input volume using the trained multi-class classifiers.
