Single Mouse Tracking Annotated Dataset
Description of Data
Information for each dataset falls into 3 folders. Filenames portray the dataset split used in the paper that they belong to (eg Training_1.png or Validation_1.png).
- Ref/*.png: Input image (image before annotation)
- Seg/*.png: Segmentation image. Values = 0 are background. Values > 0 are mouse.
- Ell/*.txt: Ellipse-fit data. Data is tab-delimited as follows:
- X Center of Ellipse (px)
- Y Center of Ellipse (px)
- Minor Axis Length of Ellipse (px)
- Major Axis Length of Ellipse (px)
- Angle Direction (Degrees). 0 is down with + values going counter-clockwise.
Standard Open Field Strain Survey
We annotated 16234 training and 568 validation images of a single mouse in the same open field. The mouse can be one of multiple coat colors, but visually appears as a black, light-grey, or white color. In total, the dataset size is approximately 1.9GB. In the case the mouse’s posture created a poor ellipse-fit, portions of the mouse were removed (such as tail) to enable a good ellipse-fit.
24Hr Open Field Dataset
We annotated 2099 training and 93 validation images of a single mouse in the same open field listed above augmented with bedding and a food container. All mice in this experiment appear black on video. There are 2 states, with visible light and with only infrared. The infrared-only imaging contains much higher visual noise.
KOMP Open Field Dataset
We annotated 1000 training and 83 validation images of a single mouse in JAX’s KOMP2 open field arena. All mice have a black coat color.
Test Ground Truth Dataset
To test the robustness of our system against conventional trackers that build a background model from multiple frames in a video, we re-sampled video a 20 minute video at 1 frame per second and annotated all the resulting frames (1179-1200 frames). We did this for the 6 environments in the paper of varying difficulty (Black, Gray, Piebald, Albino, 24Hr, KOMP2). The format of this data follows a DataSubset_FrameNumber format instead of Training/Validation_FrameNumber format.
