EPIC KITCHENS-55 Dataset
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.

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.
