| 摘 要： | 图像采集设备采集的植物叶片图像会发生几何畸变,本文提供了对畸变植物叶片图像快速几何校正的方法。首先将畸变图像进行预处理和局部阈值分割,然后提出了1种基于Hough变换求特征点的方法,最后通过空间变换和灰度差值完成了几何校正。校正结果表明此方法具有较强的可行性和有效性。 |

| Abstract: | Plant leaf image has geometric distortion because of image acquisition.An efficient method to rectify such distortion is proposed.First the distortion image and local threshold segmentation are preprocessed.Then a method is put forward to look for feature-point coordinates based on the Hough transform.Finally geometrical rectification is realized in geometrical transform and bilinear gray interpolation method and the feasibility and effectiveness of the method are validated. |
| Keywords: | Hough transformation geometrical transform gray interpolation |
