客观图像质量评价是图像处理中一项基本而又具有挑战性的工作，它能够自动地评价图像质量是否与人的感知一致。在假设任意图像失真都可以用参考图像和失真图像的方向投影图之差来表示的基础上，提出了一种新的基于方向投影的全参考模型图像质量客观评价方法。实验结果表明，所提出的度量与主观质量分数具有良好的一致性。
Objective image quality measure, which is a fundamental and challenging job in image processing, evaluates the image quality consistently with human perception automatically. On the assumption that any image distortion could be modeled as the difference between the directional projection-based maps of reference and distortion images, we propose a new objective quality assessment method based on directional projection for full reference model. Experimental results show that the proposed metrics are well consistent with the subjective quality score.
