Simulation of a retinal infrared focal plane array

摘要

Abstract: The effect of coupling/shunting network for non-uniformity correction is examined on a sequence of two-dimensional images. The results indicate that a network incorporating a resistive grid and lateral inhibition performs well if only small responsivity variations are to be remedied. In the case of hot or dead pixels (zero information artifacts), network connections must exhibit some form of adaptive capability. Parallels with known features of the human visual system are presented and discussed, specifically wash-out of images stationary relative to the retina and the related filling-in of obscurations.!10
