Abstract:
System and method for active contour segmentation where an image for a structure and an initial position on the image are received, a multi-scale image representation including successive image levels each having associated therewith a representation of the image is computed, a representation of the image at a given image level having a different image resolution that that of a representation of the image at a subsequent level, a given one of the levels at which noise in the image is removed is identified, the initial position is set as a current contour and the given level as a current level, the current contour is deformed at the current level to expand into an expanded contour matching a shape of the structure, the expanded contour is set as the current contour and the subsequent level as the current level, and the steps are repeated until the last level is reached.
