| 摘 要： | 提出了一种新的图像质量评价标准,通过图像的运动模糊参数来估计出图像由于运动而造成的信息损失量,并通过信息损失的多少来评价图像的质量。实验表明,该方法能客观地体现出运动模糊图像的质量与运动模糊参数之间的关系,这种关系对于图像的质量评价特别是有参考条件下的图像质量评价具有良好的效果。同时还根据活动度和图像灰度梯度能客观地表示图像细节部分的特性。将图像分块,并从8个方向对图像进行分析,客观地评价出无参考条件下直线运动模糊图像的质量。

| Abstract: | A new standards of image quality evaluation is presented in this paper,which estimates the information loss of the image that caused by the motion based on the motion blur parameters to evaluate the image quality.Experiment results showed that this method can reflect the relationship between the quality of motion blurred image and the motion blur parameters objectively.And it is proved to be effective especially for the reference-image.According to the active measure and gray-level gradient,it can show the ... |
