摘要
当前主流的中长波彩色融合算法中,除少数色彩映射算法以源图像差异特征为切入点,其他如色彩传递等融合算法往往损失较多差异及细节特征。主流色彩映射算法还存在偏色、色域较窄和难以适应各类应用场景等问题。针对上述问题,在以色调饱和度色彩平面为基础的色彩空间中,建立了基于差异特征的螺旋线映射理论模型,并基于此提出融合算法。对实际采集到的中长波双波段图像进行仿真验证,结果表明该算法适用于大多数复杂场景且能充分突出红外中波图像差异成分,具有更广的色域分布、更好的视觉效果和较好的客观指标评价,且计算复杂度低、实时性好。最终在嵌入式平台上完成算法嵌入,结果表明算法已具备工程应用前提。
In the current mainstream medium and long wave color fusion algorithms,except a few color mapping algorithms take the difference features of the source images as the starting point,others such as color transfer algorithms often lose more difference and detail features.However,mainstream color mapping algorithms have some problems such as color bias,narrow color gamut,and difficulty in adapting to various application scenarios.In this paper,the above problems are studied.In the color space based on a hue saturation color plane,a theoretical model of helical line mapping based on difference features is established,and a fusion algorithm is proposed based on this theoretical model.The actually collected medium and long wave dualband images are simulated and verified.The simulation results show that the proposed algorithm is suitable for most complex scenes and can fully highlight the difference components of infrared midwave images.The proposed algorithm has wider color gamut distribution,better visual effect,and better objective index evaluation,and has low computational complexity and high realtime performance.Finally,the embedding of the algorithm is completed on the embedded platform.The results show that the algorithm has the premise of engineering application.
