Abstract
Because the classic Harris corner detection algorithm calculates the corner response functions of whole pixels,it has the disadvantages of bringing about high computational complexity and is not suitable to real-time detection.a new fast corner detection algorithm was introduced to solve this problem.Given the quantity of corner makes up only a small part of the whole pixels,use four-direction brightness derivative to preliminary judge candidate comers.the threshold is the multiples of all pixels' standard deviation.After preliminarily judge,consider 8-neighborhood similarity numbers.Then,according to the numbers to re-judge candidate comers,use Harris algorithm to detect the rest of candidate corners.The experimental results showed that,the developed algorithm can improve the efficiency of its system and shorten running time of corners detection.关键词
