C语言中的图像边缘检测++
原标题:Image Edge Detection in C++

我正试图找到一种方法来确定边缘检测的正确性。我希望它有一些小标记,显示程序确定边缘的位置,比如x、点或线。我正在寻找能做到这一点的东西:http://en.wikipedia.org/wiki/File:Corner.png

问题回答

OpenCV具有边缘检测器,可在C++中使用。碰巧,您链接到的图像在描述(其中一个)内置算法的文章中使用。

您链接到ins t边缘检测的图像。

边缘检测通常只是在灰度图像中发现明显的亮度变化——你可以用差分来实现——例如索贝尔算子。

具体地说,找角要么用SIFT完成,要么用类似于高斯拉普拉斯算子的方法完成

该图像不是边缘检测操作的结果!这是拐角检测。它们有完全不同的目的:

Corner detection is an approach used within computer vision systems to extract certain kinds of features and infer the contents of an image. Corner detection is frequently used in motion detection, image matching, tracking, image mosaicing, panorama stitching, 3D modelling and object recognition. Corner detection overlaps with the topic of interest point detection.

OpenCV具有角点检测算法。最新链接包括VS 2008的源代码示例。您也可以查看此链接以获取另一个示例。谷歌可以提供更多。
