Space evaluation in football games via field weighting based on tracking data
Takuma Narizuka, Yoshihiro Yamazaki, Kenta Takizawa
In football game analysis, space evaluation is an important issue because it is directly related to the quality of ball passing or player formations. Previous studies have primaril…
Lifetime distributions for adjacency relationships in a Vicsek model
Takuma Narizuka, Yoshihiro Yamazaki
We investigate the statistical properties of adjacency relationships in a two-dimensional Vicsek model. We define adjacent edges for all particles at every time step by (a) Delauna…
Clustering algorithm for formations in football games
Takuma Narizuka, Yoshihiro Yamazaki
This paper develops a clustering algorithm for formations in team sports, with a focus on football games. Our method first clusters formations into several average formations: `442…
Characterization of the formation structure in team sports
Takuma Narizuka, Yoshihiro Yamazaki
We propose a method to identify the formation structure in team sports based on Delaunay triangulation. The adjacency matrix obtained from the Delaunay triangulation for each playe…
