Slovo - Russian Sign Language Dataset

We introduce a large-scale video dataset Slovo for Russian Sign Language task. Slovo dataset size is about 16 GB, and it contains 20400 RGB videos for 1000 sign language gestures from 194 singers. Each class has 20 samples. The dataset is divided into training set and test set by subject

. The training set includes 15300 videos, and the test set includes 5100 videos. The total video recording time is ~9.2 hours. About 35% of the videos are recorded in HD format, and 65% of the videos are in FullHD resolution. The average video length with gesture is 50 frames.

For more information see our paper - arXiv.

Downloads

Main download link

Downloads	Size (GB)	Comment
Slovo	~16	Trimmed HD+ videos by (start, end) annotations
Origin	~105	Original HD+ videos from mining stage
360p	~13	Resized original videos by min_side = 360
Landmarks	~1.2	Mediapipe hand landmark annotations for each frame of trimmed videos

Also, you can download Slovo from Kaggle.

Annotation file is easy to use and contains some useful columns, see

file:

	attachment_id	user_id	width	height	length	text	train	begin	end
0	de81cc1c-...	1b...	1440	1920	14	привет	True	30	45
1	3c0cec5a-...	64...	1440	1920	32	утро	False	43	66
2	d17ca986-...	cf...	1920	1080	44	улица	False	12	31

where:

• attachment_id
  - video file name
• user_id
  - unique anonymized user ID
• width
  - video width
• height
  - video height
• length
  - video length
• text
  - gesture class in Russian Langauge
• train
  - train or test boolean flag
• begin
  - start of the gesture (for original dataset)
• end
  - end of the gesture (for original dataset)

For convenience, we have also prepared a compressed version of the dataset, in which all videos are processed by the minimum side

. Download link - slovo360p. Also, we annotate trimmed videos by using MediaPipe and provide hand keypoints in this annotation file.

Models

We provide some pre-trained models as the baseline for Russian sign language recognition. We tested models with frames number from [16, 32, 48], and the best for each are below. The first number in the model name is frames number and the second is frame interval.
