摘　　要：提出典型场景双波段彩色融合图像颜色协调性模型,实现图像颜色质量的无参考评价.通过衡量海天、绿色植物这类自然场景融合图像颜色与对应典型类记忆色的相似度,以及选择城镇建筑物图像的最佳色彩度范围,计算三种典型场景图像色彩与场景内容的协调性;在颜色组合协调性模型基础上,将颜色区域面积之和作为加权系数构造图像中不同大小颜色区域组合加权协调性模型.主观评价实验结果表明,综合这两方面提出的协调性模型计算结果与人眼主观感受具有较好的一致性,可以有效地对典型场景彩色融合图像颜色协调性进行客观评价.For visible and infrared color fusion images of typical scenes, objective color harmony assessment models are proposed to evaluate the color quality of fusion images without reference images. The harmony between image colors and scene contents for natural scene images （green plants, sea and sky） was evaluated by measuring the similarity between image colors and memory colors of corresponding typical categories, and that for town and building images was calculated by selecting the optimum colorfulness rang. Simultaneously, based on the harmony model of color combination, the weighted harmony model for image color region combinations with different sizes was established using the areas＇ sum of color regions as the weighting. Above two aspects were combined in the proposed color harmony models for fusion images of typical scenes. Experimental results show that the proposed harmony models are consistent well with the human perception and they can evaluate the color harmony for color fusion images effectively.
