Objective Assessment of Color Harmony in Dual-band Color Fused Images
The currently available quality assessment methods for images rarely fully utilize the color coding mechanisms of the retina of human eyes and the visual cortex and fail to fully consider the influence of color information on image quality.In this study,an objective assessment model for the color harmony of visible light(dim-light)and infrared color fused images based on multiple visual features is proposed to address the above problems.This model incorporates more color information into image quality assessment by considering a variety of visual features of human eyes comprehensively,including the feature of visual contrast colors,the feature of color information fluctuation,and the feature of advanced visual content.Through feature fusion and support vector regression training,it achieves the objective assessment of the color harmony of color fused images.Experimental comparisons and analyses are conducted using databases of fused images in three typical scenes.The experimental results show that compared with the existing eight methods of objective image quality assessment,the proposed method is more consistent with the subjective perception of human eyes and has higher prediction accuracy.
