An example of our segmentation result for a heterogeneous tumor. a initial ROI. b final segmentation with our posterior probability estimation. c probability map obtained with EM. d probability map obtained with our posterior probability estimation for the initial ROI. Probability maps are shown as an RGB image for the initial ROI. Red: Normal brain tissue. Green: Abnormal brain tissue. Black: Background
