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

这篇文章,提出了一种可以精确检测椭圆特征参数的线性算子。基于双曲线模型,该算子直接检测椭圆边界附近的原始梯度信息,这样可以避免中间精确提取椭圆边缘点的过程。当计算最小代数距离时,双曲线可以受双椭圆约束。这种算法将与其他算法确定中心位置方面进行比较,我们也将通过实际实验来比较。-This article presents a precise detection of the characteristic parameters of the linear elliptic operator. Bas
