I'm looking for an algorithm to help automatically track soccer ball in a controlled field experiment (cameras positioned near to the ball) and output its time-series 2-dimensional coordinates. While we have found very efficient methods to do this in human movement features (e.g. OpenPose), we are experiencing some difficulties to found similar methods to detect/track other objects (e.g. ball). If you have some positive experiences with a given method, please let me known. Thanks in advance. Luiz H Palucci Vieira.
