Outlier Removal for Player Identification in Interactive Sport Scenes Using Region Analysis
نویسنده
چکیده
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 filters to enhance reliability. Temporal analysis of the segmentation statistics provides a strong cue to the reliability of number isolation, and confirms data integrity prior to classification. Reliable segmentation, tracking and number recognition for varying scale, orientation, and motion are shown.

Player classification in interactive sport scenes using prior information region space analysis and number recognition
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 ...
متن کاملA statistical test for outlier identification in data envelopment analysis
In the use of peer group data to assess individual, typical or best practice performance, the effective detection of outliers is critical for achieving useful results. In these ‘‘deterministic’’ frontier models, statistical theory is now mostly available. This paper deals with the statistical pared sample method and its capability of detecting outliers in data envelopment analysis. In the prese...

The analysis of coach behaviour using information and communications technology has become an established area of research. Advances in the application of information technology have lead to analysis systems for sports being integrated with match video allowing interactive video feedback to be provided in an efficient and flexible manner. Commercial video analysis packages are not only useful f...
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...
متن کاملLocal multivariate outliers as geochemical anomaly halos indicators, a case study: Hamich area, Southern Khorasan, Iran
Anomaly recognition has always been a prominent subject in preliminary geochemical explorations. Among the regional geochemical data processing, there are a range of statistical and data mining techniques as well as different mapping methods, which serve as presentations of the outputs. The outlier’s values are of interest in the investigations where data are gathered under controlled condition...
