Snapshot Safari SER (Serengeti) — Balanced Classroom Subset v1.0

Summary

A curated, balanced subset of the Snapshot Safari 2024 Expansion SER (Serengeti National Park) camera trap dataset, prepared for use in the CAS Deep Learning — Computer Vision course exercises.

Archive Images Description
ser_balanced.tar.gz 1,850 Balanced, ≤200/class, full frames

Source

MegaDetector

Pre-computed MegaDetector v1000-redwood RDE-filtered results from LILA Science: snapshot-safari-2024-expansion-SER-subset-v1000.0.0-redwood_detections.threshold.filtered.json.zip

Used to filter frames (conf ≥ 0.8) and select the best frame per sequence.

Species

buffalo, elephant, empty, gazellegrants, gazellethomsons, hartebeest, impala, warthog, wildebeestblue, zebraplains

Total 1295 278 277 1850

Note: ~56% of images are IR/night (near-infrared, nearly greyscale).

Curation Details

  • Deduplication: one image per sequence (highest MD animal confidence frame)
  • Animal filter: MD animal confidence ≥ 0.8
  • Empty filter: max MD animal confidence < 0.2
  • Split strategy: stratified 70/15/15 by sequence ID — no sequence spans splits
  • Image resolution: resized to max 1024 px on longer side, JPEG quality 92
  • Format: ImageFolder layout — <split>/<label>/<filename>.jpg
