Claim One:
1. A method for interactive level set image segmentation, comprising: selecting and labeling by user input respective image areas of object and of background; initializing an embedding function φ for implementing a segmenting boundary in accordance with said user input; computing intensity distributions p 1 and p 2 by performing a kernel density estimate of intensity distributions associated with said respective areas of object and of background; and performing repeatedly steps (a), (b), (c) and (d) below until convergence is reached: (a) evolving said embedding function φ in accordance with an evolution equation, (b) recomputing said distributions p 1 and p 2 , and (c) if a new user input is found, updating labeling of said areas of object and background and returning to step (a) and, if no new user input is found, then ending.
