基于快速SIFT特征提取的模板匹配算法
Template Matching Algorithm Based on Fast SIFT Feature Extraction
摘要
Abstract
According to the problem of large amount of Scale Invariant Feature Transform(SIFT) algorithm, this paper constructs pyramid feature descriptor by using concentric squares, calculates every seed vector quickly by using recursion algorithm, and maintains the rotation invariant of algorithm by simply ranking the vector. It puts forward a matching search method which is suitable for the descriptor. Experimental results show that the algorithm can increase the matching speed, and can identify target effectively under rotate and zooming.关键词
