    As tremendous improvement in computer vision technology, various industries start to apply computer vision to analyze huge multimedia content. Sports as one of the biggest resource invested industries also step up to utilize this technology to enhance their sports intelligent products. The thesis is following this development to provide prototype implementations of computer vision algorithms in sports industry. Main objective is to develop initial algorithms to solve play-field detection and player tracking in basketball game video. Play-field detection is an important task in sports video content analysis, as it provides the foundation for further operations such as object detection, object tracking or semantic event highlight and summarization. On the other hand, player tracking highlight player movements in critical events in basketball game. It is also a challenging task to develop effective and efficient player tracking in basketball video, due to factors such as pose variation, illumination change, occlusion, and motion blur. This thesis proposed reliable and efficient prototype algorithms to address play- field detection and single player tracking. SURF algorithm is utilized and modified to offer precise location of play-field and overlay trajectory data to improve viewer’s experience on sports product. And compressive tracking algorithm implemented for the aim of capture and track single player in important events to reveal player’s secret tactics. Prototype implementation to meet the current needs in basketball video content analyzing field
