The Softball Pitching Plane (SPP): A Reliable Geometric Descriptor of Arm Trajectory and Its Relationship to Ball Velocity in Adolescent Pitchers

Applied Sciences
This study introduced Softball Pitching Plane (SPP), a best-fit geometric plane designed to characterize the throwing arm spatial trajectory during the windmill softball pitch. The purpose was to evaluate the reliability of this planar representation and

Return Temporal Anticipation On The Basis Of The Ball Trajectory Estimation [PDF]

, 2010
Odehrání míče v tenise vyžaduje především prostorově-časovou informaci o dráze letu míče. Ve výzkumu jsme se zaměřili na časovou složku při riternu. Pomocí nahrávacího stroje jsme simulovali podání soupeře.

Using physics simulations to find targeting strategies in competitive tenpin bowling

AIP Advances
A new approach to finding the ideal location for a bowler to target on a bowling lane is demonstrated. To model bowling ball behavior, a system of six coupled differential equations is derived using Euler’s equations for a rotating rigid body.

A Catching Ball System with Prediction on Trajectory of the Flying Ball

, 2016
When humans catch a ball, they will first predict the landing point, then move to the nearby position to catch the ball. If the ball is thrown from a lomg distance, then they slowly adjust the prediction point.

Trajectory-based ball detection and tracking with applications to semantic analysis of broadcast soccer video

, 2003
This paper first presents an improved trajectory-based algorithm for automatically detecting and tracking the ball in broadcast soccer video. Unlike the object-based algorithms, our algorithm does not evaluate whether a sole object is a ball. Instead, it
