The binary joint transform correlator (BJTC) can provide sub-pixel correlation location accuracy for a pair of almost identical inputs, as is the case when computing the registration offset between two overlapping images from the same sensor. Applications include noise cancellation, motion compensation, super-resolution processing, and image splicing. We experimentally demonstrated sub-pixel registration and image co-addition. Our results show a resolution improves by a factor of almost two compared to normal integration. This paper details early results in an ongoing project.
