摘　　要：利用多波段偏振图像可以有效地区分人造目标与自然场景,提出利用IHS(彩色空间)变换与小波变换相结合的多波段偏振图像融合方法,使得在融合后的偏振图像I、Q、U中,包含了具有相同偏振特征、不同光谱特征的目标信息,同时能够更加细致、全面的描述场景中的目标;实验结果表明,融合后的偏振图像不仅反应了场景的偏振信息,而且包含了丰富的光谱信息,目标与背景的对比度也得到了增强,为进一步的目标检测和识别提供了便利。Multi-band polarimetric images can be used to discriminate man made targets from background. A multi band polarimetrie image fusion method based on the combination of the IHS and wavelet transforms is proposed, which makes fused polarimetric images I, Q, U contain most targets in the multi-hand with the same polarization and different speetral information, and the targets in the backgrounds is presented more meticulous and comprehensive. The experimental result shows that the fused images can present the polarization information, acquire more spectral information and higher contrast, and object detection and recognition can be more easy by using fused images.
