Morphological filtering as template matching
R. Jones, Imants Svalbe · IEEE Transactions on Pattern Analysis and Machine Intelligence · 1994
Binary morphological operations with single and multiple structuring elements are implemented using look-up table (LUT) driven templates. Many complex operations can be implemented in one pipeline processing cycle for 3*3 regions of support and in four or five cycles for 5*5 regions of support. The basis representation of the operations is used to specify the required templates.>
