The Algorithm of Caption Detection for Soccer Video
Jingyu Yang · Manufacture Information Engineering of China · 2006
The appearance of caption is quite common in the soccer video and usually accompanies the occurrence of soccer event. So the caption detection can be used as one of useful context cues in the inference of soccer event. According to the characteristic of soccer video from the World Cup, it presents the caption detection algorithm based on the projection and connectivity information. The approach steps include: the gray-level projection statistic, caption positioning, connectivity analysis, region adjusting and caption verification. The proposed algorithm involves the multiple parameters and the method of data training. In the experiment the game video of World Cup 2002, it evaluates the detection performance, the results show that the algorithm is effective.
