We have two Chinese sign language datasets for isolated Sign Language Recognition and continuous Sign Language Recognition, respectively. Both datasets are collected with Kinect 2.0 by 50 signers. Each signer perfors 5 times for every word (sentence). The sign videos are recorded with 30fps. The distance between the signers and Kinect is about 1.5 meters. Each instance in both datasets contains RGB videos, depth videos, and 3D joints information of the signer.

Since the dataset is recorded with Microsoft Kinect, there are three data modalities available:

  1. RGB videos with resolution of 1280 x 720 pixels and frame rate of 30 fps.
  2. Depth videos with resolution of 512x 424 pixels and frame rate of 30 fps.
  3. Twenty-five skeleton joints locations of each frame.

Isolated SLR

If you use this Chinese isolated SLR dataset in your research, please cite the following papers:

The isolated SLR dataset contains 500 Chinese sign words. Each sign video is performed by 50 signers with 5 times. Hence, there are 250 instances for each sign word.

You can download the RGB and Depth videos of the dataset here Isolated SLR500 (RGB & Depth, 1 time each signer), or Isolated SLR500 (RGB, 5 times each signer) [password: rvux].

Besides, the signer's skeleton joint information is available here Isolated SLR500 (Joints). [password: fwt7]

Continuous SLR

If you use this Chinese continuous SLR dataset in your research, please cite the following papers:

Besides, you can refer to the following papers for continuous SLR published by our group:

The corpus of continuous SLR dataset contains 100 Chinese sentence. There are 250 instances (50signers x 5times) for each sentence.

You can download the RGB videos of the continuous SLR dataset here Continuous SLR100 (RGB). [password: ac52]
