- 指南针边缘检测算法是当前质量最高的边缘检测方法,比CANNY算子效果还要好。具有边缘定位准确,边连续,完整的特点。程序能够得到每一个像素的边的朝向,有利于做进一步的优化应用,例如图像分割等。具体算法过程可参考斯坦福大学麦克博士发表的论文。主要思路就是以每个像素为中心,像罗盘一样转动边,一直找到两边差异最大的朝向。最后把所有的最优朝向连起来成为边缘。 代码用VC驱动,核心部分用matlab编写-Compass edge detection algorithm is currently the

- 在图象中,边缘是由灰度级和相邻域点不同的象素点构成的。因而,若想增强边缘,就应该突出相邻点间的灰度级的变化。微分运算可用来求信号的变化率,因而具有加强高频分量的作用。如果将其应用在图象上,可使图象的轮廓清晰。由于我们常常无法事先确定轮廓的取向,因而挑选用于轮廓增强的微分算子时,必须选择那些不具备空间方向性的和具有旋转不变的线形微分算子。-In the image, the edge is adjacent to the gray-scale and different domains consi

- 提出了一种基于图像边缘连接的线段检测方法。数字图像中的线段是由很多线段图元组成,在同一 条线段中,它们的方向是相同的并且受到真实线段的方向约束。因此可以通过提取小的线段图元, 然后分析它们 的连接特性, 进行线段的检测。首先用ADM 算法对图像进行边缘检测, 得到单像素宽的边缘 然后在4 个方向上 进行线段的检测 对初步得到的结果进行合并和验证, 去掉短的线段, 连接临近的线段。经过实验证明, 该方法能 够快速地提取图像中的线段,并且对噪声具有一定的鲁棒性-A line seg
