基于伪彩色编码和图像融合的伪装目标识别方法

A Disguised Target Recognition Method Based on Pseudo-color Coding and Image Fusion

结合基于IHS空间的伪彩色编码技术和图像融合技术,提出一种可用于快速识别伪装目标的方法。对某一场景的红外热像进行基于IHS空间的伪彩色编码,分别得到明度、色调和饱和度分量;再将同一场景的可见光图像与红外图像作基于区域能量的小波图像融合,得到新的明度值;通过IHS-RGB转换,得到一幅结果图像。通过仿真实验可知:通过结果图像,不仅可以快速识别伪装的目标,而且可判断出目标的位置。

A method to recognise the disguised target is proposed on the basis of the techniques of pseudo-color coding and image fusion. Pseudo-color coding is done to the infrared image to get the intensity, hue and saturation. Then the new intensity that is created by the wavelet image fusion based on region energy replaces the old intensity component. At last, the IHS-RGB transform is done to get the result image. It can be concluded through the emulational experiment that not only the disguised target can be recognized soon,but also the position information of the target can be known from the result image.
