This Matlab/C code contains routines to perform level set image segmentation according to:



(1) various multiphase (multiregion) formulations, including a fast scheme where the computation load grows linearly with the number of regions and,



(2) various region-based image descr iptions which generalize the standard piecewise constant Chan-Vese model the descr iptions include Gamma distribution models for image data corrupted by multiplicative noise as in remote sensing synthetic aperture radar (SAR), and medical imaging ultrasound. Also included is kernel mapping as an alternative to explicit image modeling.-This Matlab/C code contains routines to perform level set image segmentation according to:
