Wear Santa Hat

• This project based on opencv and qt.

Introduction:

It was very hot recently, so I decided to write one with the help of OpenCV face detecter and trained model data (haarcascade_frontalface_alt2.xml). The face detecter in OpenCV occupies a lot of memory, but it's hard for me to make a face detecter by myself. I will make a simple one when I'm free.

好像这个最近挺火的，顺手写了一个，用的是OpenCV自带的人脸检测和训练好的数据（haarcascade_frontalface_alt2.xml）,感觉OpenCV的人脸检测有点占内存，但是自己写的话很慢，又要训练，等有时间自己写一个简单点的人脸检测吧。
