Abstract
Space-variant sensors are of great importance in both machine and biological vision, and they have superior imaging property than the rectilinear sensors during high-speed forward motion. We focus on the modulation transfer function (MTF) of a particular spatially variant sampling retina-like sensor, pixels of which are arranged in a log-polar fashion. The 3D MTF of the sensor has been built using Hankel Transformation (HT) based on sampling and imaging property of the sensor. Moreover, the output image is simulated in the light of MTF. This research helps to model the imaging process of an imaging system containing retina-like sensor.
