摘要相比于灰度图像，人眼对彩色图像更敏感，彩色化红外图像有利于人眼在夜间识别目标，因此研究红外彩色化很有意义。本毕业论文研究了单通道红外彩色化以及双通道融合彩色化。对于单通道彩色化，着重研究了三种伪彩色处理算法，经Matlab仿真，分析彩色化结果，连续编码彩色的结果更加适合于人眼观察。在分析红外和微光图像各自特点的基础上，研究了三种双谱融合彩色化算法，包括直接和线性组合映射融合彩色化，基于拮抗视觉特性的彩色化，颜色迁移彩色化。经仿真分析结果，和伪彩色相比，融合彩色化的图像信息比较丰富；和映射融合相比，基于拮抗模型的彩色化图像颜色比较柔和；经过颜色迁移处理的图像具有了自然感。最后，研究了在FPGA上进行红外视频实时彩色化处理。19128

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.
