| Abstract: | Feature point is a key local feature of image,and feature point extration is an important step of image registration based on the feature points.Through the feature point extration and processing, it has the important practical significance for grasping the local and general characteristics of the image ,especially for image registration and target recognition,etc .This paper introduces several popular methods of feature points, and analyzes the advantages and disadvantages.By experiments, some feature point detection methods are compared by means of evaluation factors,which has certain directive significance for image recongistion. |
