Distance accumulation and planar curvature
Jing Han, Timothy Poston · 2002
The authors present a method, called distance accumulation, of computing features of closed planar boundaries of 2-D digital images, or closed curves. Distance accumulation is computed by accumulating the distance from a point in the boundary to a chord specified by moving end points. Experimental results with simulated and real images showed its robustness. The analysis of its relation to planar curvature matches experimental results well. >
