Abstract
A method of automatically recognizing objects in a digital image. The pixel coordinates of the boundary of the objects are identified and stored as data. A series of Fourier coefficients describing the boundary of the object are calculated and used to generate a set of descriptors. The descriptors are stored and compared with similarly generated descriptors of other objects to determine correspondence therebetween.
