Claim One:
1. A computer-implemented method for active contour segmentation of imaging data, the method comprising: (a) receiving at least one image for a given structure and obtaining an initial position on the image; for each one of the at least one image, (b) computing a multi-scale image representation comprising a plurality of successive image levels each having associated therewith a representation of the image, a representation of the image at a given one of the plurality of successive image levels having a different image resolution than that of a representation of the image at a subsequent one of the plurality of successive image levels; (c) identifying a given one of the image levels at which noise in the image is substantially removed; (d) setting the initial position as a current contour and the given image level as a current image level; (e) deforming the current contour at the current image level to expand into an expanded contour matching a shape of the given structure; (f) setting the expanded contour as the current contour and the subsequent one of the plurality of image levels as the current image level; and (g) repeating steps (e) and (f) until a last one of the plurality of image levels is reached.
