Abstract

The correlation of several 1-D projections of a 2-D image are considered for pattern recognition. A theoretical analysis and SNR comparison to 2-D correlations are provided with successful simulated results that show that the use of two or three 1-D correlations can identify and discriminate the 26 characters in the alphabet. Several possible 1-D optical correlators to implement projection correlations are described.
