In this paper, a new methodology for computing orientation of a gray-tone image by the method of moments is described. Orientation is an essential feature needed in many image processing and pattern recognition tasks. Computation of moments is accomplished by a new projection method that leads to a fast algorithm of determining orientation. Using a simple architecture, the proposed algorithm can be implemented as a special purpose VLSI chip. The hardware cost of the proposed design is significantly lower compared to that of the existing architecture.
