27
+ ## Dataset Details
28
+ This readme contains information about video files. Please see the
29
+ [github](https://github.com/epic-kitchens/annotations) for the latest annotations
30
+ and challenges for the dataset.
31
+
32
+ ## Folder Details
33
+ We have the following top level folders:
34
+
35
+ * **videos:** contains the raw uncut videos.
36
+ * **object_detection_images:** contains the frames used as input for object
37
+ detection.
38
+ * **rgb_flow:** contains the RGB and flow frames used as input for action
39
+ recognition.
40
+
41
+ We use `P##/P##_**` with `##` denoting the participant number and `**` to denote
42
+ the video number.
43
+
44
+ ### Video Folder Structure
45
+ Videos is further broken down into two subdirectories, train and test containing
46
+ the files in the train and test sets respectively.
47
+
48
+ Each video, labelled as `P##_**.mp4` can be found inside the participant
49
+ directory, i.e. `P01_01.mp4` can be found at `Videos/train/P01/P01_01.mp4`.
50
+
51
+
52
+ ### Object Images Folder Structure
53
+ Object Detection Images is further broken down into two subdirectories, train
54
+ and test containing the files in the train and test sets respectively.
55
+
56
+ Image frames, labelled as `img_xxxxxxxxxx.jpg` can be found inside the video
57
+ directory, i.e. The first frame from `P01_01.mp4` can be found at
58
+ `ObjectDetectionImages/train/P01/P01_01/img_0000000001.jpg`.
59
+
60
+
61
+ ### RGB Flow Folder Structure
62
+ RGB Flow is further split into two subdirectories, `rgb` and `flow` containing
63
+ files for the RGB frames and flow Frames. Both folders contain the same
64
+ directory structure and are further broken down into train and test directories
65
+ containing the train and test sets respectively.
66
+
67
+ Frames from a video have been grouped into a tar file, labelled as `P##_**.tar`
68
+ and can be found inside the participant directory, i.e. The RGB frames from,
69
+ `P01_01` can be found in `rgb_flow/train/P01_01.tar`. Similarly the flow frames
70
+ can be found in `flow/train/P01_01.tar`. Each tar file contains a flat directory
71
+ of frames named `frame_xxxxxxxxxx.jpg`.
72
+
73
+
74
+ ## Video Information
75
+
76
+ Videos are recorded in 1080p at 59.94 FPS on a GoPro Hero 5 with linear field of
77
+ view. There are few videos which were shot at different resolutions,
78
+ field of views, or FPS due to participant error or camera. These videos
79
+ identified using `ffprobe` are:
80
+
81
+ * 1280x720: `P12_01`, `P12_02`, `P12_03`, `P12_04`.
82
+ * 2560x1440: `P12_05`, `P12_06`
83
+ * 29.97 FPS: `P09_07`, `P09_08`, `P10_01`, `P10_04`, `P11_01`, `P18_02`,
84
+ `P18_03`
85
+ * 48 FPS: `P17_01`, `P17_02`, `P17_03`, `P17_04`
86
+ * 90 FPS: `P18_09`
87
+
88
+ The GoPro Hero 5 was also set to drop the framerate in low light conditions to
89
+ preserve exposure leading to variable FPS in some videos. If you wish to
90
+ extract frames we suggest you resample at 60 FPS to mitigate issues with
91
+ variable FPS, this can be achieved in a single step with FFmpeg:
92
+
93
+ ```
94
+ ffmpeg -i 'P##_**.MP4' -vf 'scale=-2:256' -q:v 4 -r 60 'P##_**/frame_%010d.jpg'
95
+ ```
96
+
97
+ Optical flow was extracted using a fork of
98
+ [`gpu_flow`](https://github.com/feichtenhofer/gpu_flow) made
99
+ [available on github](https://github.com/dl-container-registry/furnari-flow).
100
+ We set the parameters: stride = 2, dilation = 3, bound = 25 and size = 256.
