This paper introduces the Polar-Mellin transformation for distortion-invariant pattern recognition with emphasis on the implementation of the Polar-Mellin transform by a computer-generated optical element and by a special TV camera. When the computer-generated optical element or the TV camera for the polar-ln transform is used for correlation
the pattern which is interested can always be recognized even though the pattern is rotated or seale-changed or shifted. In this paper
two kinds of distortion-invariant systems for pattern recognition using the computer-generated optical element and the TV comera are given. Computer simulations and primary experiments have proven that methods described in this paper are correct.
