| 摘 要： | 针对离散曲率不能很好地表达图像像素变化的问题，提出了一种度量图像像素陡变程度的方法，该方法利用某一点与其前后点形成的2个矢量，定义后一矢量相对于前一矢量变化的角度弧度值为该点的陡变度。实验证明，陡变度比离散曲率能更好地反映图像像素变化。 |

| Abstract： | This paper uses examples to illustrate the fact that discrete curvature can not show the change of image pixels perfectly. To solve this problem, the paper comes up with a method to measure the sudden change degree. The method makes use of one certain point and two vectors which are organized by the chosen point and other two points before and behind the certain point. And then, the paper gives the definition that the point’s sudden change degree is just the changing angle which made by the latter vector comparing to the former vector. The experiment results show that the sudden change degree can better prove the change of image pixels than discrete curvature. |
