The authors concentrate on regularizing the differentiation operation and incorporating it in an edge-detection scheme. They describe a method for differentiation that addresses its susceptibility to noise, using the language of well-posed and ill-posed problems. Both a direct implementation of Miller regularization and one involving projections onto convex sets are considered. Examples are presented that indicate some directions for future efforts.
