摘要
基于特征的图像配准方法作为一种重要的图像配准方法,是近年来图像配准技术的研究热点。本文对BRISK算法进行了详细的描述。详细介绍了FAST角点特征提取算法、尺度空间构造以及尺度空间关键点检测方法、关键点描述方法和特征点匹配算法,给出了算法实现基本流程图。
Image registration is a hot spot in the field of image processing and computer vision.It is the prerequisite for a successful application of the image reconstruction,image mosaicing,and so on.it finds wide application in this field.It is analyzed the common error sources in Image registration.With the study of image registration recently,based on the characteristics of image registration method is becoming important.Brisk algorithm is described in this paper.It is introduced the corner FAST feature extraction algorithm,space structure and scale space key point detection method,description method and key point feature point matching algorithm,it draws algorithm flow chart.
