Robust Detection of Corners and Corner-line Links in Images [PDF]
2010 10th IEEE International Conference on Computer and Information Technology, 2010 We define corner points in an image as the intersections among detected straight line segments, and propose an algorithm that detects corners from such a definition. Our corner detection algorithm CLDC then makes use of the LDC (Line Detection using Contours) algorithm from [19], which outputs the list of all detected line segments together with their ...
