The white line marks on the soccer playfield can convey the positional information of the ongoing match. In this paper, we propose a new algorithm for automatic, robust line mark recognition for soccer video and its application in camera calibration is also investigated. The line mark recognition consists of four steps, playfield region detection, playfield area analysis, edge pixel detection and...
On one hand, goalmouth detection is a kind of high-level semantic concept detection methods in sports video, on the other hand, data mining for video processing that can benefit video analysis is a promising research frontier. In this paper, a robust method is proposed to detect the presence of goalmouth in field-ball game video based on fuzzy decision trees. Balance process is added in training procedure...
Video shot boundary detection is an essential step for video browser and retrieval. Most shot detection methods detect cut translation without difficulty, but gradual translation is regarded as a hard problem. An approach for video shot boundary detection that can detect gradual transitions in addition to abrupt cuts is proposed. In our approach, the difference between two frames is measured by mutual...
