Research questionHow can individual animals be counted across sparse camera-trap frames when tracking labels are scarce?Camera traps often capture short bursts at roughly one frame per second, so detections must be linked across widely separated images to avoid double-counting or missed individuals. Most datasets lack the tracking annotations needed to learn these associations.

Latest papersRecent research connected to this question, newest first.PuTR-CouT: Counting-by-Tracking in Camera-Trap Image SequencesThe evidence concerns multi-species counting on the iWildCam 2021 benchmark. It describes a transformer-based association tracker trained partly with synthetic pseudo-tracking labels derived from static backgrounds and short temporal bursts, and reports competitive results against an improved MaxBoxCount baseline, with track-level verification.research paper · Sep 4, 2026
