【摘要】 颜色作为描述图像最直接有效的特征,是目前图像质量评价中备受关注的评价参数之一。提出一种基于颜色特征的全参考图像质量评价系统,该系统在结构相似性SSIM(Structural Similarity)理论的基础上,充分考虑色度信息对人眼视觉感知的影响,利用分块颜色矩,建立了一种新的相似度度量模型。实验结果表明,该模型获得的客观评价结果与主观评价值具有很高的一致性。更多还原

【Abstract】 As the most direct and efficient features to describe images,color features currently become one of the most significant parameters in image quality assessment.Based on the theory of structural similarity,a model of full-reference objective quality assessment system for image on the basis of color features is proposed,which takes the affect of chrominance on the human visual perception into consideration.After the theoretical analysis,a new similarity model using color moments of partitions is established in this paper.Experimental results show that the model has high consistency with the subjective results.更多还原
