This paper describes and deduces the theory of Haar-like features, Integral image and AdaBoost algorithm, which were proposed by Paul Viola, and then researches its improvement. We combine Microsoft Visual C++6.0 with OpenCV Function library to develop the software, and achieve the function of real-time face detection. According to experimental results, we can conclude that the improved algorithm...
This paper presents a long distance person identification system based on height measurement and face recognition using web-camera without zoom-in/zoom-out. In this system, face detection determines if a target person entering the monitoring area or not. We use calibrated camera technique to compensate distortion images. Human height is then measured by the ratio with a reference point. The measured...
