摘要
平面非规则曲线的识别与匹配主要用于图像识别、物体匹配等领域。在综合研究比较国内外的研究成果后,提出了一种新的快速提取特征进行筛选而后进行细节比对与匹配的方法。该方法首先通过提取构成平面非规则曲线的一系列离散点的关键特征进行快速筛选,而后逐步比对细节特征,分析其变化趋势,对平面非规则曲线的匹配有着较为满意的匹配效果。该方法相比现有的匹配方法,具有识别与匹配速度快,准确率高,适应性强等优点。
Quick recognizing and matching of planar irregular curve is mainly used in image identification and object＇s matching. This paper presents a new approach which extracts key features quickly and then matches details after researching and comparing products.The result of this method is content to planar irregular curve recognizing and matching by abstracting key features of a series of discrete points which makes up the planar irregular curve to choose quickly,and then comparing detail features,analyzing fluctuation tendency.h is proved that the gived method is stable,efficient and applicable.
