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

首先关于图像处理软件opencv进行总的介绍，然后分别对其中的人脸检测原理、计算机视觉、Harr特征级联表、非固定大小目标检测步骤、拉普拉斯边缘检测及opencv的其他特性作了一定的介绍-General introduction to the first image processing software opencv face detection principle, computer vision, Harr, characteristics of cascade table, fixed-

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
