Binary matrices of optimal autocorrelations as alignment marks

Computer Vision and Pattern Recognition 2023-05-03 v1 Information Theory math.IT

Abstract

We define a new class of binary matrices by maximizing the peak-sidelobe distances in the aperiodic autocorrelations. These matrices can be used as robust position marks for in-plane spatial alignment. The optimal square matrices of dimensions up to 7 by 7 and optimal diagonally-symmetric matrices of 8 by 8 and 9 by 9 were found by exhaustive searches.
