Abstract

In this paper, a new system for calculating the geometric moments of an input image is presented. The system is based on a mathematical relationship that relates the geometric moments of the input image to the intensity of the Fourier transform of the image. A digital post-processor performs a differentiation process on the sampled Fourier intensities to obtain a set of values which are combined in a pre-determined fashion to provide the geometric moments of the original input function.
