【摘要】 提出一种新的图像质量的客观评价方法,该方法用图像梯度幅值的累加和作为衡量图像质量的指标,无需原始图像作参考,适合于两幅以上同源图像对比来相对地评价图像质量。实验结果表明,该方法所用的指标能比较准确地反映图像的质量,符合人眼的视觉特征,且计算简单,易于快速实现。更多还原

【Abstract】 A new method for objective assessing image quality is presented.This method is based on gradient magnitude. and does not need the original image for reference. It is suitable for comparing two or more same images which have different qualities. Experimental results show that the proposed scheme is effective. It is in accordance with the conventional subjective method in most of the cases, and is easily implemented.更多还原
