Abstract
Analysing basketball player movement is not performed conventionally recently. Combining science and technology in sport has made a great impact. Basketball player movement analysis using latest technology can achieved by many ways such as retrieving information from video. A video that contains basketball match can be valuable resource to be analysed by computer vision technique. Player movement estimation can be separated into two categories such explicitly or implicitly. Player movement estimation that is performed implicitly is assumed more efficient than explicitly one, but in consequent, it has exploiting series computation like Lagrangian or Eulerian to the pixel color value and it is not easy to be seen by human visual system. This paper uses Eulerian series because of its succest in the previous research activity that called eluerian video magnification technique. That technique is implemented to basketball player in the field and it is not easy task because it is the object is formed as group in certain environment.
Highlights
A precision in player position and movement in video after mapping is crucial to know (Fig. 1)
Implementation of object detection based HSV and object detection based PCA still does not get better result for player movement that will be transformed into mapping
This paper shows implementation of Eulerian series in pixel color value that generated by Taylor series expansion or eulerian video magnification that developed by Wu et al[1]
Summary
A precision in player position and movement in video after mapping is crucial to know (Fig. 1). That precision must be resulted from exact position and direction of movement at one player in the field. Implementation of object detection based HSV and object detection based PCA still does not get better result for player movement that will be transformed into mapping. There is still missing detection on some players (Fig. 2). It must be a disadvantage because analysis of basketball playing using video processing can not be done properly. It is important to know because playing style of each player is a very important study material for a team who will play with another team
