虽然cascade classifier的HOG特征在3.x版本是不能用了(2.4版本还是可以的),但是可以用opencvsamples/cpp/train_HOG.cpp(或者是这个库) 首先需要编译.cpp文件获得.o文件(编译opencv的sample文件可以看这里): g++ `pkg-config--cflags--libsopencv` -o train_HOG opencv/samples/cpp/train_HOG.cpp 训练: train_HO...
opencv_haartraining 和 opencv_traincascade使用不同的文件格式保存训练过的分类器。注意,新的级联检测接口(见类CascadeClassifier,objdetect模块)支持两种格式。opencv_traincascade可以保存(导出)旧格式的训练结果。但两者在中断后,不能load(import)彼此的文件格式.(But opencv_traincascade and opencv_haartraining can not ...

opencv_traincascade训练出的分类器是新结构的，关于能否用CvHaarClassifierCascade加载，目前并不确定。不过，你可以尝试使用CascadeClassifier进行加载，因为这个类能够兼容老版本的分类器。如果你坚持要用CvHaarClassifierCascade加载的话，可以考虑通过运行opencv_haartraining.exe来重新训练分类器。这样生成的分类器...
OpenCV ships with an application that can be used to train acascade classifier. The steps to prepare your data and train the classifier can be quite elaborate. I have detailed the steps that I used below to train the classifier to identify an object (say car): ...
Opencv 2.4.2 is used to implement the haar cascade classifier. We achieved 100% face detection rate on Indian database containing simple background and 93.24% detection rate on Caltech database containing complex background. Haar cascade classifier provides high accuracy even the images are highly...
Face Recognition using Haar-Cascade Classifier, OpenCV, and Python (2) Requirement Python 3.5 OpenCV 3.1.0 Numpy (3) Tips 1、you need set up "mysql-essential-5.1.73-win32.msi" on your server, because some data i will insert into facedb; 2、set up mysql then python can connect mysql ...

In this guide, we've used OpenCV to perform Object Detection in Python, using the Haar-Cascade Classifier. We've been introduced to the classifier, Haar features and performed object detection on images, videos in real-time as well as a video stream from a webcam!
After a classifier is trained, it can be applied to a region of interest in an input image. The classifier output is a 1 if the region is likely to show the object; otherwise, it is 0. Let’s see how we can use the Haar Cascade detection in OpenCV. ...
