Researchers have developed a new benchmark for detecting tennis events, such as ball bounces and racket hits, from video footage. This benchmark includes 345 frame-level annotations across various camera viewpoints, including broadcast, elevated, phone, and court-level perspectives. Existing supervised spotters perform well on broadcast footage but poorly on other angles, while a new arbitration layer, RallyArb, shows promise by maintaining a high bounce detection F1 score across different camera types, though it struggles with precise timing.
