摘要
提出了一种基于链码的圆形目标分析方法,通过链码计算圆形目标的面积和周长,进而计算其圆形度和半径,并对圆形度进行规一化,从而可对目标进行有效的分析。该方法计算速度快,占用内存小,检测分析性能较高。
In the image processing and analysis,some circle objects are often detecteded and measured.The conventional Hough transform has the limitation of too much computation and memory space,so it is difficult to be used in real-time system.In this article,an analysis method based on chain code to circle object is put forward.The area and perimeter of circle object are calculated based on chain code.,then the circle alike parameter and radius are acquired,at the same time,the circle alike parameter is normalized.A...
