Joint label fusion is for combining candidate segmentations produced by registering and warping multiple atlases for a target image. Corrective learning can be applied to further reduce systematic errors produced by joint label fusion. In general, corrective learning can be applied to correct systematic errors produced by other segmentation methods as well. 2013-8-29 picsl_malf_1.3 2013-3-15 picsl_malf_1.2 2012-9-05 1.1 PICSL Multi-Atlas Segmentation Tool Segmentation, Atlas Application, Domain Independent, GNU General Public License (GPL), Multiple Sclerosis,
