Abstract

Coded aperture imagery poses a challenge for traditional image tracking algorithms because of the highly distributed nature of the coded imagery. Traditional algorithms would require this imagery to undergo a computationally expensive decoding operation before subsequent processing and tracking. In this paper, a novel tracking algorithm is described that can track point-source targets at sub-pixel accuracy without requiring the coded aperture imagery to be decoded. Furthermore, it is shown that the algorithm is robust to changes in the coded aperture mask pattern, and so is suitable for use in adaptive coded aperture imaging systems. Some results of the algorithm on synthetic and initial MWIR experimental data will be given.
