Research of Digital Simulation for Low-light-level night vision Imaging System

摘要

Construct the transform function model of low-light-level night vision imaging system and its components; Convert the input image with a certain pattern through FT to get the frequency spectrum of it, and filter the frequency spectrum of input image by use of the transform function model. And then, convert the filtered frequency spectrum of input image through iFT to get the filtered image. Thus, implement the digital simulation of low-light-level night vision imaging system by computer.
