A Badminton Recognition and Tracking System Based on Context Multi-feature Fusion
This work provides a domain-specific solution for sports video analysis, focusing on badminton, and is incremental as it builds on existing methods with contextual multi-feature fusion.
The paper tackles the problem of detecting and tracking badminton balls in sports video analysis, addressing challenges like small size and fast movement, and achieves results such as 100% precision and 84.1% F1-measure in occlusion-free data.
Ball recognition and tracking have traditionally been the main focus of computer vision researchers as a crucial component of sports video analysis. The difficulties, such as the small ball size, blurry appearance, quick movements, and so on, prevent many classic methods from performing well on ball detection and tracking. In this paper, we present a method for detecting and tracking badminton balls. According to the characteristics of different ball speeds, two trajectory clip trackers are designed based on different rules to capture the correct trajectory of the ball. Meanwhile, combining contextual information, two rounds of detection from coarse-grained to fine-grained are used to solve the challenges encountered in badminton detection. The experimental results show that the precision, recall, and F1-measure of our method, reach 100%, 72.6% and 84.1% with the data without occlusion, respectively.
