摘要
通过对两类样本的详细地分析,本文提出并设计了基于关键点特征的十字架提取检测算法,实验证明了该算法对第一类样本是有效的;在此基础上,分析了该算法对第二类样本的不适用情况,提出了改进算法,即基于点线复合特征的十字架提取检测算法,经试验,该算法运行速度快,成功率高,对两类样本适用性较好。
Through analyzing two samples, this paper puts forward a method according to the key orders the cross of the characteristic withdraws the calculate way, experimenting the proof that calculate way valid to the first sample. Then, analyzed that calculate way to the obsolescent circumstance of the second sample, put forward the improvement calculate way according to order the cross of the compound characteristic in line withdraw the calculate way. Through experiment, this calculate way circulates the speed quick, succeed the rate high, is better to two samples applicability.
