A computer algorithm is described that extracts the edge information from a digital image of an AP radiograph of the knee. Automated image field partitioning is used as a simplifying first step in the process. Methods that employ a priori knowledge are used to insure simple connected edges.
Computer diagnosis, edge detection, feature extraction, Gaussian weighting, radiographs.
