一种积分图的分治计算方法
A Divide and Conquer Calculation Approach of Integral Graph
摘要
Abstract
This paper proposes a method to calculate integral images on part of the image instead of global scope by hardware, thus avoiding most time-consuming pretreatment. The cost of doing so and the speed of single rectangular feature calculation are acceptable due to the characteristic of AdaBoost that few rectangular features are needed to drop out most unrelated images. With traditional AdaBoost, this method can accelerate the analysis of a great number of high-resolution images. As result, when irrelative image occupies 98% of whole, the performance of this approach will be 31.8% higher than traditional ones.关键词
