Directional Search for Spiral Trajectory Extraction
Xiao Fang Shao, Hong Chen · Applied Mechanics and Materials · 2015
Spiral trajectory curves often occur in modern production lines. In this paper we propose a curve inference method for spiral trajectory extraction. Based on the tensor voting result of the original images, the method performs a post-processing stage and a directional neighborhood searching process which takes into account the turning angle of the pixels on a certain curve. At last the method is tested on several real images.
