Abstract

The use of chord distributions in pattern recognition is discussed and efficient ways to compute such distributions are noted. New methods to achieve scale and in-plane rotational distortion-invariant multi-class recognition and estimates of the distortion parameters are described. 3-D out-of-plane rotational distortion-invariant methods are reviewed.
