Improvement of the OPTA algorithm and its application in remote sensing images thinning

LI Er-sen①,ZHANG Bao-ming①,GUO Hai-tao①,ZHOU Xiao-ming①,CHU Yan-feng①②,CHEN Ke①(①Institute of Surveying and Mapping,Information Engineering University,Zhengzhou 450052,China;②65015 Troops,Liaoning Dalian116023,China)  
On the basis of analyzing and studying the quick thinning algorithm and the OPTA thinning algorithm,it is known that the thinning result of the quick thinning algorithm is not single pixel and the templates of the OPTA thinning algorithm is not optimized.So a method to overcome the shortcomings of the OPTA thinning algorithm is proposed and some thinning templates are redesigned.Through experiments,the new algorithm has been proved to fulfill the basic needs of the thinning algorithm,it guarantees that the width of the line is single pixel,maintains the connectedness of the original image.The effects of the new algorithm are evidently improved.
