| 摘 要： | 采用索贝尔算子检测边缘,最大类间方差法把图像二值化,通过数学形态学处理得到改进的二值图像,掏空内部点得到边界点,进行边界跟踪把轮廓从复杂的图像中提取出来。传统的边缘检测得到的边缘不一定是单像素点,而此方法实现单像素点的轮廓提取,实验证明该方法行之有效。 |
| 关 键 词： | 边缘检测 阈值 数学形态学 方向链码 轮廓跟踪提取 |

| Abstract: | Sobel operator is use to detect edge and the method of maximum classes square error binarizes images.Binary images are obtained after handled by mathematic morphology and followed along the border finally,with the contour drawn out from the complicated picture.The edges obtained by traditional edge detection might not be single pixel points and single-pixel-point contour extraction with this method has been proved to be effective. |
| Keywords: | edge detection threshold mathematics morphology direction chain yard contour following and drawing |
