| 摘要: |
| 在图像分割和边缘检测的基础上，根据云南黑籽南瓜苗的几何形状特性，给出了用解析几何法寻找生长点位置的方法，这种方法计算速度快、鲁棒性好。认为可以用偏心率作为区分是瓠瓜苗还是南瓜苗的特征值，实验结果表明区分成功率可达到90％。 |

| Abstract: |
| Based on the image segmenting and edge detecting, a geometrical algorithm isdeveloped to search for the growth point of the Yunnan black-seed pumpkin seedlingaccording to its shape features. Eccentricity can be used to identify the pumpkin seedlingfrom cucurbit. Experiments show that the ratio of successful differentiation is over 90%. |
