| 摘 要： | 分水岭算法作为彩色图像分割手段的一种方法，具有运算简单，性能优良，能较好提取运动对象轮廓和准确得到运动物体边缘等优点。应用分水岭算法研究了绿色作物及其背景的分割，首先通过数码相机拍摄的一幅640×480田间青菜真彩色图像，在matlab中采用分水岭分割算法处理图像后提取其绿色分量，再用数学形态学闭运算处理后可以较好地分割绿色作物与背景。针对结果中存在的过分割现象，采用先计算图像的形态学梯度，再用分水岭算法分割可以使结果得到有效改善。

| Abstract: | As a algorithm of true color image segmentation,watershed segmentation has less computation,better performance,which can also obtain profile and edge of mobile object.The algorithm was used for segmentation green corps from background for its performance.At first,a true-color greengrocery image of 640 pixels width and 480 pixels height obtained by digital camera,which was processed by morphological watershed in the software of matlab.The greengrocery and background was segmented by extracting its green vect... |
