Title The Research and Implementation of colorizing infrared image
Abstract
Compared to graycsale images,the people’s eye is more sensitive to color image,colorizing infrared image is beneficial to identify target in the night ,so the research of colorizing infrared image is significant.This paper studies the colorization of single-channel image and fusion of two-channel images.for single-channel colorization, We focus on the three algorithms of pseudo-color processing.we analyze the results by Matlab simulation ,and discover that the result of continuous color code is more comfortable to people’s eyes.Based on the analysis of the respective characteristics of infrared and low-vision image,we studies three algorithms about double-spectral fusion colorization,including colorization of direct and linear combination of fusion,colorization based on opponent visual model,and colorization based on color migration.It shows,by analyzing the simulation results,that compared to pseudo-color,the information of the fusion images is rich,the color of the image based on opponent visual model is relatively soft compared to the mapping fusion,the image contains natural color through the color migration.Finally,We studies real-time colorizing infrared video on FPGA.
