Application background
The statistics system of the classroom can accomplish the real-time statistics of the number of the classroom, and it is one of the key factors that can improve the teaching quality and students' learning life. This article involves the classroom number statistics system, due to the required identification of the classroom environment is more complex and accurate results can be obtained, so should choose relatively robust algorithm to calculation and statistics.The system implementation using QT and C + + language development, and combined with the opencv open source computer vision library, finally completed a complete to count the number of applications of image, video and camera respectively. In this paper are introduced in detail knowledge of Haar like features and the integral image method, and the AdaBoost algorithm to establish their own sample database for training a cascade classifier using the Haar classifier to complete the system oc++
