基于Gabor滤波器的特征抽取技术

Feature Extraction Techniques Based on Gabor Filters

首先简介了2D Gabor函数,然后从样点的选取、Gabor滤波器参数设置、Gabor特征后处理等方面,综述基于Ga-bor滤波器的特征抽取技术,最后给出进一步的研究方向.

First this paper introduces briefly 2D Gabor functions.Then it reviews the feature extraction techniques based on Gabor filters,including selection of sample points,parameters-setting of Gabor filter,postconditioning of Gabor features,and so on.Finally,it proposes further research directions.
