It is a utility to control screen saver using human face detection. Human face detection is performed using OpenCV Haar-Cascade method. The software is primarily a daemon that resides in your system tray and keeps observing the input from a webcam to

介绍了人脸检测的算法，然后分析人脸检测算法在CPU上执行的效率，最后找到在GPU上利用OpenCL并行优化基于haar层级分类器的通用方法，从比较宏观的角度介绍了优化方法，给出了基于图像金字塔和级联分类器的算法的通用优化方法-Introduced face detection algorithm, and then analyze the face detection algorithm running on the CPU efficiency, and finally found the G

haar特征的提取，haar特征目标动态检测，非常适合需要的人在此的基础上改进的，希望对能帮助大家(Haar feature extraction, Haar features, target dynamic detection, very suitable for those who need improvement on this basis, and I hope to help you)
