| 摘 要： | 为了测试改进后的程序,原始网格图和变形网格图皆由计算机生成。在生成变形网格图时,考虑了刚体移动、刚体转动、一般变形这三种变形,另外还生成一幅中间缺少网格点的大变形图像。结果表明:在不同的变形情况下,尤其在中间缺少网格点的大变形下,虽然网格点分布不规则,但是程序仍然能够自动分割、编码,而且准确无误;呈二值化分布的网格点误差为0.0058像素以下,呈高斯分布的误差为0.00076像素以下。 |

| Abstract: | In order to checkup program, original grid image and deformation grid image are made by computer. The rigid body move, the rigid body turn and the common deformation are considered in making deformation grid image, and the big deformation grid image lack in a few points is also made. The results indicate: in cases of different deformations, especially in case of big deformation grid image lack in a few points, although points in grid image are irregular, program can segment and encode automatically and accurately; the error of points with two-digit distribution is under 0. 005 8 pixel , and the error of points with GAUSS distribution is under 0.000 76 pixel. |
