Speed Up Robust Feature Algorithm by OpenCV it can detected specified image and matching I adjust it to use a cam so it runs in real time but I guess it doesn t look so fast,Speed Up Robust Feature Algorithm by OpenCV it can detected spe

Harris，FAST，Eigen 3种特征点提取方法的比较，开发平台是vs2005和opencv-Harris, FAST, Eigen 3 kinds of feature point extraction method comparison, the development platform is vs2005 and opencv

首先使用FAST对图像进行特征点提取，之后生成ORB描述符，进行点特征匹配，可以达到快速精确配准-The first to use the image FAST feature point extraction, after generating ORB descr iptors were point feature matching, can achieve fast and accurate registration

图像特征提取是计算机视觉和图像处理中的一个概念。它指的是使用计算机提取图像信息，决定每个图像的点是否属于一个图像特征。包括：Harris角点、ShiTomasi角点、亚像素级角点、SURF角点、Star关键点、FAST关键点、Lepetit关键点等等(Image feature extraction is a concept in computer vision and image processing. It refers to using a computer to extract imag
