Shape recognition plays an important role in machine vision applications. The effective recognition algorithm should be less complicated and more accurate. In this paper, a structural descriptor for shape recognition is presented which has less complexity and more accuracy comparing with existing algorithms. Obviously, the boundary of shape is an important property in shape representation and description...
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...
