Image rotation-elimination based on the retina-like sensor

Abstract

The pixels of the retina-like sensor are arranged in different concentric rings, and its output image is in log-polar coordinate. Thus additional residual errors will not be produced when the output image is rotated. Therefore, the retina-like sensor has obvious advantages and wide prospect to be applied in the fields of image rotation and rapid image rotation-elimination. In this paper, a theory concerning the image rotation of the retina-like sensor is proposed, and a solution based on the theory is presented and realized for image rotation-elimination. Several image rotation-elimination experiments have been done, and it turns out that the solution is simply, accurate and rapid.
