图像特征点提取方法对比及特征点匹配方法

特征点提取方法

官网的文档

对特征的理解 Understanding Features

harris特征点 Harris Corner Detection

Shi-Tomasi特征点 Shi-Tomasi Corner Detector & Good Features to Track

FAST特征点  FAST Algorithm for Corner Detection

SIFT特征点 Introduction to SIFT (Scale-Invariant Feature Transform)

SURF特征点  Introduction to SURF (Speeded-Up Robust Features)

BRIEF BRIEF (Binary Robust Independent Elementary Features)

ORB  ORB (Oriented FAST and Rotated BRIEF)

匹配方法  Feature Matching

举例 Feature Matching + Homography to find Objects

 opencv视频获取

sift理论知识可以参考这篇文章Sift算子特征点提取、描述及匹配全流程解析

用到的关于Mask参考的文章详解掩膜

ORB参考文章ORB 一种特征匹配替代方法：对比SIFT或SURF

Numpy参考 多维数组的切片(slicing)和索引(indexing)
