A novel, to our knowledge, method of distortion-invariant
three-dimensional (3-D) pattern recognition is proposed. A
single two-dimensional synthetic discriminant function is employed as a
reference function in the 3-D correlator. Thus the proposed system
is able to identify and locate any true-class object in the 3-D
scene. Preliminary simulation and experimental results are
