HW1-1

Although this course use different computer language, but I think it is really interesting and not too difficult for us at this part. Original I think only can show one screen from one webcam at each time, now I know we can just write some code to let we can show so many image at once. And I learn "CvCapture" means to connect to video, "IplImage" is about the image, and what's cvFlip mean.
