视频比赛分析
我期待找到一种算法来检测给定视频文件中的模式。实际上，我将索引网球比赛视频中发球（进球后的第一脚）的时刻。
PS1：抱歉英语不好。 PS2：我对网球一无所知，除了你需要一个球才能打！！
I am looking forward to find an algorithm to detect a pattern in a given video file. Actually I am going to index moments in a tennis match video at which service (first kick after a goal) is shot.
PS1: sorry for broken English.
PS2: I DO NOT know anything about tennis except that you need a ball to play!!

看看 opencv
对于视频流中的网球，我会简单地匹配一小块白色像素，然后将其与运动预测结合起来（球必须接近并位于从最后一帧开始的连续路径上）
Take a look at opencv
For a tennis ball in a video stream I would look at simply matching a patch of white pixels, then combine this with movement prediction (the ball has to be close to and on a continual path from the last frame)
网球？目标？你是说服务？谷歌 OpenCV。您在模式识别或图像处理领域有过经验吗？我建议你调查一下他们。
一般来说，在大多数涉及球的运动中，您都希望以某种方式跟踪它。您可以在应用一些过滤器后使用边缘检测算法来完成此操作。
我强烈推荐学习 O'reilly 出版商的 OPENCV。非常好的书，还解释了图像处理概念。
你的项目雄心勃勃！这很好。首先了解你的概念，然后这一切就会变得很容易！祝你好运！
Tennis? Goal? You mean serve? Google for OpenCV. Have you got any experience in the field of pattern recognition or image processing? I suggest you look into them.
Generally in most sport involving a ball you are looking to track it in some way. You can use edge detection algorithms after applying a few filters to accomplish this.
I would highly recommend learning OPENCV by O'reilly publishers. Very good book that also explains image processing concepts.
Your project is ambitious! Which is good. Learn up your concepts first then all this will seem very easy! Good Luck!
