摘要
在多视点图像系统中,由于场景光照或相机标定的原因,通常会导致同一对象在不同视点位置颜色外表的不一致。传统的亮度补偿算法难以有效地解决这个问题。基于Retinex颜色恒常性理论,提出了一种新颖的多视点图像规正算法,通过直方图均衡化、Retinex处理和颜色恢复手段,提取出反映物体本质特征的反射光系数来消除不一致光照的影响,在增强单视点图像对比度的同时,将视点间图像的颜色规正到一致的水平。
Because of scene illumination or camera calibration,the color appearance of the same object between different view-points will be different in multi-view images system.Tradition illumination compensation algorithm for image is unable to solve this problem effectively.ln this paper,a novel multi-view images color correction algorithm is proposed based on retinex color constancy theory.Histogram equalization,retinex processing and color restoration are performed for multi-view images,and extract reflectance which describe object intrinsic properties to eliminate un-consistent light source influence.The experimental results show that corrected images not only have high color contract,also have consistent color appearance with others.
