Player classification in interactive sport scenes using prior information region space analysis and number recognition
نویسندگان
چکیده
This paper proposes using a novel region space technique to track sport persons for the purpose of extracting their shirt numbers and use this to provide augmented information to the viewer. The region adjacency graph and picture trees are used to perform a search for an object using prior knowledge from a scene description. Once the candidate object has been extracted the subspace is examined for alphanumeric characters, which are then characterized by optical character recognition. Rogue candidates may be removed based on the recognition histograms with improved robustness using temporal analysis.

Outlier Removal for Player Identification in Interactive Sport Scenes Using Region Analysis
This paper demonstrates the use of segmentation, tracking, and number recognition of sport players for the provision of augmented information in moving sequences. Using prior knowledge of colour distribution the players and associated numbers are extracted for characterisation. The optical character recognition algorithms exploit multiple instances of the same character applying temporal filter...
متن کاملSegmentation and Tracking For Interactive Sport Scenes Using Region Adjacency Graphs, Picture Trees and Prior Information
Tracking of video objects in pixel space using block based methods or template matching suffers from boundary alignment problems, assumes knowledge of object location, and is severely effected by rotation and shear. This paper suggests a region domain based object tracking algorithm. Using region adjacency graphs it is proposed to perform the search in region space, using relational information...

Activity recognition in sport is an attractive field for computer vision research. Game, player and team analysis are of great interest and research topics within this field emerge with the goal of automated analysis. As the execution of same activities differs between players and activities cannot be modeled by local description alone, additional information is needed. Inspired by the concept ...
