Abstract
We present an integral descriptor whose value is invariant with respec t to translation, rotation, and scale changes of an object. The descri ptors of objects in the input scene can be presented as correlation pe aks by means of optical correlators. A triple-invariant pattern recogn ition method is proposed based on the descriptor. To improve the discr imination, the use of a descriptor vector is suggested.
