一种基于色彩变换的伪彩色图像融合新算法

伪彩色处理对目标的识别与跟踪十分有意义。图像融合是伪彩色处理的非常有效的方法之一。本文提出了一种基于伪彩色的图像融合新方法。用小波变换得到灰度融合图像,求出灰度融合图像与原图像的差异图,利用IHS变换,得到彩色融合图像,再经过色彩变换,得到最终的伪彩色融合图像。结果表明,融合图像色彩更逼真,更符合人眼的视觉特征。

A Novel Pseudo-color Fusion Scheme Based on Color Transfer Algorithm

The pseudo-color processing is useful for object detection and tracking.Image fusion is an effectual scheme for pseudo-color processing.In the paper,a novel pseudo-color image fusion method based on color transfer is proposed.With wavelet transfer,the grayscale fusion image is formed.Then two images showing differences between two original images and grayscale fusion image are generated.These two images including differences and the grayscale fusion image are sent to I,H,S color channels respectively.At last,with color transfer,the final pseudo-color fusion image is formed.The experimental results show that the algorithm can give grayscale image a natural color appearance.
