Extraction of Connected Edges from Knee Radiographs
July 1972 (vol. 21 no. 7)
pp. 753-758
D.A. Ausherman, Departments of Electrical Engineering and Radiology, University of Missouri
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.
Index Terms:
Computer diagnosis, edge detection, feature extraction, Gaussian weighting, radiographs.
