基于图像边缘区的图像评价方法

Evaluation method based on the image edge

通过对图像处理中的缩放算法得到的图像误差进行分析,发现图像误差主要集中在图像边缘区,进而提出了基于边缘稳定的图像评价方法,实验表明,该方法符合人的主观视觉质量需求.

The image error analysis which is acquired from the image zooming algorithm in pro-cessing reveals that the image errors are mainly in image edge area. Then, we provide an evalua-tion method based on the image edge stability. The result of experiments shows that the method is consistent with the perceived image quality.
