Tao Hou · Jisuanji gongcheng · 2011
Aiming at the problem that traditional vector recognition algorithm has and low recognition efficiency,this paper uses a new method to recognize the digitized curves which is based on sparse pixel traversal tracking fitting algorithm.The algorithm operations with orthogonal pixel tracking style to obtain key points data of graphics area,then the obtained points are used to make curve fitting to uniformly perform the recognition of line segments,circles and arcs,et al.Experimental results show that this algorithm is more efficient and effective compared with conventional methods,especially on the consumed time and space.
