Several edge detection algorithms are examined for their utilities in edge or surface searching in medical images. Algorithms that are under study include those methods developed by Sobel, Roberts, Kirsch, Marr-Hildreth, Haralick, Shen-Castan, and Nalwa-Binford. An example of boundaries detected by applying these algorithms to brain images acquired by various imaging modalities is presented.
