Sports match video keeps most information in the games. In this talk, taking badminton as an example, we will introduce how deep learning and machine learning can help in the collection of microscopic data from sports match video. In addition, some interesting results of tactical analysis will be given.
Sports activities entertain people and play an import role in our daily life. For professional athletes, pre-match strategic analysis may bring information to break opponent's tactics and be the key to win the tight games. In this talk, taking badminton as an example, we will introduce how deep learning and machine learning can help in sports tactical analysis.
To enable tactical analysis, data collection is a prerequisite. Since video keep rich visual information, it is considered as the log of video sensors and can help in data collection. First of all, we will survey techniques of computer vision, deep learning, and machine learning that can be used to extract microscopic data from video for tactical analysis. The techniques including homography mapping, tiny object tracking, human skeleton detection, depth map prediction, etc. will be covered.
The second topic is tactical analysis. Statistic methods will be used to reveal overall information. Pattern discovery algorithms will be used to find the ball usage pattern. Spatial analysis will be used to understand the mobility of athletes. Visualization techniques will be applied to help in data mining and effective communication between athletes and their coaches.
### What Will Be Covered?
* Computer vision for sports applications
* Tracking high speed and tiny objects from broadcast video
* Deep learning networks for human skeleton detection and depth map prediction
* What is shot-by-shot microscopic data?
* Tools for labeling shot-by-shot microscopic data
* Ball type classification
* Analysis of running speed
* Analysis of ball usage patterns
### Potential Audience
* People who are interested in the applications of computer vision, deep learning, and machine learning.
* People who are interested in video-based data collection.
* People who are interested in sports tactical analysis.
* People who want to develop video labeling tools.
