摘要
针对红外图像和可见光图像的成像特点,提出了一种红外与可见光图像融合方法。首先,采用改进的区域生长法,提取红外图像目标区域。将提取到的红外目标区域映射到可见光图像中,进行一次局部信息融合。然后,将第一步的融合结果与原始红外图像通过一种边缘增强的小波变换融合法得到最终的融合图像。实验结果表明,该方法得到的融合图像红外热目标突出、背景清晰,具有良好的目视效果。
Aiming at the characteristics of infrared and visible images,a novel fusion algorithm is proposed . Firstly,the infrared image target region is extracted by using an improved region growing algorithm and is mapped to the visible image for local information fusion .Then,the obtained fusion image is fused with the original infrared image by using a wavelet transform method based on edge enhancement to generate the final fusion image .Experimental results show that the fused image obtained by the proposed algorithm can highlight the infrared image target and reserve the clear background with good visual effects .
