Missouri Camera Traps


This data set contains approximately 25,000 camera trap images representing 20 species (for example, the most common labels are red deer, mouflon, and white-tailed deer). Images within each sequence share the same species label (even though the animal may not have been recorded in all the images in the sequence). Around 900 bounding boxes are included. These are very challenging sequences with highly cluttered and dynamic scenes. Spatial resolutions of the images vary from 1920 × 1080 to 2048 × 1536. Sequence lengths vary from 3 to more than 300 frames.

Data format

Annotations are provided in the COCO Camera Traps .json format used for most data sets on lila.science. Note that due to some issues in the source data (see below), bounding boxes are accurate, but for images that have multiple individuals in them, a bounding box is present for only one. For these images, we have added a non-standard field to the .json file (“n_boxes”) which indicates the number of animals that actually exist in the image, even though a bounding box is present for only one. We hope to fix this at some point, and it’s only 79 images, and we know exactly which ones they are (here’s a list), so if someone wants to send us updated bounding boxes for those images, we will (a) update the .json file and (b) buy you a fancy coffee.

Annotations are also provided in the whitespace-delimited text format used by the authors (inside the zipfile, along with a README documenting its format), though we recommend using the .json file; the filenames in the text file don’t correspond precisely to the image filenames, and (as per above) most images that have multiple animals include redundant bounding boxes, rather than multiple unique bounding boxes.

Downloading the data

Images are available in the following cloud storage folders:

  • gs://public-datasets-lila/missouricameratraps/images (GCP)
  • s3://us-west-2.opendata.source.coop/agentmorris/lila-wildlife/missouricameratraps/images (AWS)
  • https://lilawildlife.blob.core.windows.net/lila-wildlife/missouricameratraps/images (Azure)

A link to a zipfile is also provided below, but – whether you want the whole data set, a specific folder, or a subset of the data (e.g. images for one species) – we recommend checking out our guidelines for accessing images without using giant zipfiles.
