摘要
针对多孔径雷达(SAR)图像和红外图像的特点,提出一种基于稀疏表示的SAR/红外图像彩色融合方法。该方法首先采用稀疏表示获得SAR图像和红外图像的灰度融合图像;其次在YCbCr空间采用基于颜色传递的彩色融合方法,生成两幅图像的初始彩色融合图像;最后在YCbCr空间利用两幅图像的灰度融合图像代替其初始彩色融合图像的Y分量,得到最终的近自然彩色融合图像。实验表明该方法获得的彩色融合图像具有较好的亮度对比和细节信息,图像色彩更易于人眼观察,同时增强了对场景的理解和目标探测。
Considering the features of SAR image and infrared image ,an image fusion and colorization method based on sparse representation and color transfer is proposed in this paper .Firstly ,the grayscale fused image of SAR image and infra-red image is gained based on sparse representation .Secondly ,the initial color fused image is gained by matching the statistics of target image and the reference image in the YCbCr color space .Finally ,the final color fusion image is obtained by repla-cing the luminance component with the grayscale fused image during the color transfer process .The experimental results show that the proposed algorithm can obtain the perfect contrast and detail information ,and the color of the fusion image is comfortable for human eyes .The situation awareness and target detectability can be enhanced by the method .
