1. A method for multi-label image segmentation, comprising:
- receiving image data including a set of labeled image elements;
mapping a change in intensities of the image data to edge weights;
determining potentials for each image element in the image data; and
assigning a label, based upon the determined potentials, to each image element in the image data.

33. A method for semi-automatic multi-label image segmentation, comprising:
-
acquiring image data;
marking the image data to include a set of labeled image elements;
mapping a change in intensities of the image data to edge weights to represent the image data with random walker biases;

assigning a label, based upon the determined potentials, to each image element in the image data; and
outputting a segmentation of the image data including the assigned labels.
