opencv:cv2.goodFeaturesToTrack Scale-Invariant Feature Transform(SIFT):在图像大小改变时角点检测的效果就不好了,Lowe提出了一个描述图像里与角度大小无关的关键点的方法。在opencv3中,SIFT在contrib模块里,ubuntu环境安装opencv_contrib的方法见我写的教程。windows的话,opencv3.2中集成了contrib,可以在这里找到对应的wh...

在PL-VIO中直接调⽤了OpenCV旧版本的LSD线段检测器 #include<opencv2/line_descriptor/descriptor.hpp> using namespace cv::line_descriptor;但可能由于著作权等⼤⼈的原因,OpenCV3.4.6及以后版本已经将LSD线特征提取算法从代码中剔除了。因此我们可以选择使⽤旧版本的OpenCV,亦或者基于新版本OpenCV把原LSD...

OpenCV有这样一个函数,cv.goodFeaturesToTrack(). 他可以N个强角点在图像中,这个函数使用了Shi-Tomasi的方法(或者是Harris的,如果你想的特殊化的话)。通常,图像应该是灰度图像。然后,要定义好要找的角点的数量。然后,您指定质量级别,该值是介于0-1之间的值,该值表示每个角落都被拒绝的最低角点质量。然后,我们提供...

In this paper, we present a means of detecting and tracking a face and its features. There are many possible applications for our findings such as gaming, conferencing, and handicapped assistance. Our method of detection and tracking uses OpenCV to load boosted Haar classifier cascades which allow...
A stand-alone application has been developed to provide an overall test bench for all algorithms, realized by OpenCV implementations. Experiments show that the Karhunen Loeve Transform-based Tracker is the most consistent and effective tracking algorithm. Considering external disturbances, template matching...
