Theory of matrix morphology
Stephen S. Wilson · IEEE Transactions on Pattern Analysis and Machine Intelligence · 1992
The current concept of mathematical morphology (called scalar morphology here) is extended to a matrix morphology formalism. A formal definition of matrix morphology on binary images is followed by a complete pictorial example of a nontrivial application. Binary matrix morphology is extended to gray-scale matrix morphology using a traditional development. General window transforms are expressed in terms of matrices. An application to character recognition is given.>
