基于特性分析的SURF加速方法研究
RESEARCH ON SPEED-UP METHOD OF SURF THROUGH PROPERTIES ANALYSIS
摘要
Abstract
To resolve the problem of a little bit low speed the typical image feature extraction algorithm SURF (speeded up robust feature) has, in the paper we do an in-depth analysis on the algorithm properties in regard to its running time, instruction type, memory access, hot spots,and etc. On this basis, we optimise the SURF algorithm by reconstructing the judgment logic, the memory accessing and data organisations,the library functions implementation and other strategies. Moreover,we analyse the role of speedup of each optimisation strategy on the algorithm through experiments. And experimental data show that these optimisation strategies can effectively improve the running efficiency of SURF in the premise of guaranteeing 100% accuracy of the algorithm, and 2. 75X ultimate performance improvement is achieved.关键词
