Patent ID: 7565009

Claim:
A method of identifying an object in a digital image, comprising the steps of: providing to a computer a digital image comprising a plurality of intensities corresponding to a domain of points in a N-dimensional space; providing to the computer a point in the image that is a concentration location; using the computer to initialize a cluster with said concentration location; using the computer to add the neighboring points of the concentration location to a list; using the computer to select a neighbor point with an extremal potential value from said list and removing said selected point from said list; using the computer to determine a slide direction of all neighbors of said selected point and identify those neighbors that slide to the selected point; using the computer to add those neighbor points not already in the list to the list; using the computer to add the selected point to the cluster; and repeating the steps of using the computer to select a neighbor point with an extremal potential value, determine a slide direction, add points to the list, and add the selected point to the cluster, until the list is empty.
