Robust Image Corner Detection Based on Multi-scale Curvature Product
Xiaohong Zhang · 2007
The technique of multi-scale product corner detection is proposed in the framework of curvature scale space(CSS).A scale product function is defined as the multiplication of the curvatures of the contour at each scales.Corners are constructed as the local extreme points by limiting the scale product results.The most significant property of the scale product that it has to effectively enhanced curvature extreme peaks while can suppress noise and improve localization.The detection and localization performance analysis of the scale product are performed according to consistency of corner numbers(CCN) criteria.Experiments also demonstrate that the method has the detection results of good quality and strong robustness against noise.
