Abstract
One of main tasks in machine vision is able to provide understandable descriptions of objects. A method described here is based on fast Fourier descriptors, which initially incorporated with classic image processing operation can describe shape information in feature space. Fourier descriptor based on chain code and Fourier Transform method is discussed and related invariant property is derived. Experimental results verify good performance of fast Fourier descriptors for shape recognition applications.
