This is a project with complete C++ code that helps you using haar-like feature to training things you intrested like hands or faces.This project requires opencv 2.1 libs and VS2008.
This document describes how to train a classifier for object detection. OpenCV comes already with a trained classifier for frontal face detection. In order to show that it also works for a variety of objects, not only for faces, an exemplary trainin
2002年Rainer Lienhart对此方法进行了扩展,增加了倾斜特征的定义.此后此方法才被扩展到全旋转缩放情况下的人脸检测.以下是这位大牛发表于2002年的两篇文章之一: An Extended Set of Haar-like Features for Rapid Object Detection
