Title    Color Night Vision Algorithms Based on EMCCD
Abstract
Under the development of EMCCD and the application of color night vision,this paper studies color night vision algorithms based on EMCCD.Firstly,the paper introduces the development of EMCCD and color night vision technology at home and abroad and summarizes the imaging principle of EMCCD and the existing algorithms of color night vision.Then, we propose a interpolation algorithm based on hue consistency and a correction algorithm based on edge for Bayer color filter sampling images.By the comparison with traditional bilinear interpolation about the signal to noise ratio of various components,MATLAB simulation results show that this algorithm is better than bilinear interpolation in hue improvement.For the fusion of low light level images and infrared images,this paper adopts a median filtering algorithm in the low light level image preprocessing.This algorithm is better than the median filter function of MATLAB.We use second degree statistics of co-occurrence matrix to evaluate fused images.The maximum value method, average method ,regional analysis method and principal component analysis method are introduced in the wavelet domain  for image fusion.Meanwhile, the fusion algorithm of Laplace and FSD in Pyramid are compared.The color transfer algorithms based on statistics transfer in the wavelet domain and histogram matching are proposed on the basis of a series of fusion algorithms.Simulation results show that  the energy, contrast and resolution of images by color transfer  can be improved.
