摘　　要：通过采用简单、基于增强处理和HSV变换、基于人眼视觉特性及YIQ变换的彩色融合得到4幅图像,分别对其进行主观和客观评价.主观评价实验对同一场景的可见光、中波红外和长波红外图像进行了不同的算法处理,将获取结果用于直方图统计对比分析.客观评价采用基于YIQ变换及加权平均的方法进行图像比较,并直接用对比度R、粗糙度G和熵B比较融合结果,提出应采用主、客观结合的评价方法.Four color fusion images are subjectively and objectively evaluated. The images are obtained from the simple color fusions based on enhanced treatment and HSV transform, human visual characteristics and YIQ transform. In the Subjective evaluation test, the visible image, medium-wave image and long-wave image in the same scene are processed according to different algorithms. The results are used to analyze comparatively statisti- cally the histograms. In the objective evaluation test, the images are compared through ways of YIQ transform and averaging, and then the fusion results are compared using directly contrast degree of R channel, rough de- gree of G channel and entropy of B channel. Conclusion is that the combination of subjective evaluation and objective evaluation can effectively evaluate the color fusion images.
