CircleCI GitHub release arXiv-1804.02748 Data

EPIC-KITCHENS-55 is the largest dataset in first-person (egocentric) vision; 55 hours of multi-faceted, non-scripted recordings in native environments - i.e. the wearers' homes, capturing all daily activities in the kitchen over multiple days. Annotations are collected using a novel `live' audio commentary approach.

Dataset Details

Ground Truth

We provide ground truth for action segments and object bounding boxes.

  • Objects: Full bounding boxes of narrated objects for every annotated frame.
  • Actions: Split into narrations and action labels:
    • Narrations containing the narrated sentence with the timestamp.
    • Action labels containing the verb and noun labels along with the start and end times of the segment.

Dataset Splits

The dataset is comprised of three splits with the corresponding ground truth:

  • Training set - Full ground truth.
  • Seen Kitchens (S1) Test set - Start/end times only.
  • Unseen Kitchens (S2) Test set - Start/end times only.

Initially we are only releasing the full ground truth for the training set in order to run action and object challenges.

Important Files

Additional Files

We direct the reader to RDSF for the videos and rgb/flow frames.

We provide html and pdf alternatives to this README which are auto-generated.

File Downloads

Due to the size of the dataset we provide scripts for downloading parts of the dataset:

Note: These scripts will work for Linux and Mac. For Windows users a bash installation should work.

These scripts replicate the folder structure of the dataset release, found here.

Video Information

Videos are recorded in 1080p at 59.94 FPS on a GoPro Hero 5 with linear field of view. There are a minority of videos which were shot at different resolutions, field of views, or FPS due to participant error or camera. These videos identified using ffprobe are:

  • 1280x720: P12_01, P12_02, P12_03, P12_04.
  • 2560x1440: P12_05, P12_06
  • 29.97 FPS: P09_07, P09_08, P10_01, P10_04, P11_01, P18_02, P18_03
  • 48 FPS: P17_01, P17_02, P17_03, P17_04
  • 90 FPS: P18_09

The GoPro Hero 5 was also set to drop the framerate in low light conditions to preserve exposure leading to variable FPS in some videos. If you wish to extract frames we suggest you resample at 60 FPS to mitigate issues with variable FPS, this can be achieved in a single step with FFmpeg:

ffmpeg -i "P##_**.MP4" -vf "scale=-2:256" -q:v 4 -r 60 "P##_**/frame_%010d.jpg"

where ## is the Participant ID and ** is the video ID.

Optical flow was extracted using a fork of gpu_flow made available on github. We set the parameters: stride = 2, dilation = 3, bound = 25 and size = 256.
