摘要
In this paper, an effective system consisting of four subsystems is proposed to bowling game video indexing by integrating the visual and the auditory information The lane boundary information is extracted first to assist in all the events detection For throwing clip event, the auditory temporal property is further employed to aid in the detection A new bowl positioning model is designed to derive the bowl trajectory, which solves the obstacle using the perspective projection model with the absence of related camera parameters Also, a new, feasible and reliable approach to identifying the delivery time event through detecting the delivery prompt lights is proposed A more reliable feature in the color information of the pin mark compared with the intensity edge is exploited to identify the bowling pin Connecting all the pin mark positions called pin-mark curve can be generated such that the exact position for each pin can be determined with integrating the pin arrangement rule The users can effectively query specific interesting events including a bowl throwing clip, a bowl trajectory, delivery time and a bowling result via the proposed system The experimental results Indicate that our system can achieve satisfactory performance in events detection
