Retina based sampling in face component recognition.
Masters thesis , Eötvös Loránd University, Budapest.
Abstract
We examine a combined sampling technique suggested by well-known properties of the human retina, such as the greatest visual acuity in the center (fovea) and exponentially decreasing resolution toward the periphery. We modelled the high resolution part with uniform sampling, and log-polar sampling was applied at the periphery. The aim of the paper is to investigate whether this retinotopic sampling gives rise to a considerable deterioration in eciency compared with the commonly used uniform and log-polar techniques in case of face component recognition task on the FERET database. We have found that it certainly does not have considerable drawbacks, moreover it seems to be favourable in the present task.
