Paper Abstract

Most of the published work about SKIPSM (Separated-Kernel Image Processing using finite-State Machines) has concentrated on large-neighborhood operations (e.g., binary morphology, Gaussian blur), because the speed improvements are the most dramatic in such cases. However, there are many frequently, used 3 X 3 operations that could also benefit from speed improvements that arise from separability and the use of finite-state machines. This paper shows SKIPSM implementations for an extensive list of 3 X 3 operations, including various edge detectors, connectivity detectors, direction of brightest neighbor, largest gradient, and direction of largest gradient. A generic implementation applicable to all 3 X 3 binary operations, whether separable of non-separate, is also given.
