Sports TT Analysis

Sports TT Analysis

Very good paper

TTNet: Real-time temporal and spatial video analysis of table tennis

Notes

  • Tracking of players 
  • Sports equipment (like balls or hockey sticks)
  • Human pose estimation 
  • Multiple levels of detection of game-related actions

  • Ball Detection from Top View
  • Ball Detection from full table side view
  • Player Body Segmentation
  • Action Recognition
  • Semantic masks of the table, humans, and scoreboard as well as the ball position
  • Second stage of the ball detection is introduced. 
  • Event spotting - According to the table tennis rules, only ball bounces, serves, and net hits are essential to keep the score updated
  • The required semantic masks of three classes (humans, table, scoreboard) 
  • Ball detection by the global detector were achieved in the case of the longest 9-frame sequences

More Experiments

Keep Thinking!!!
