It is important to note that due to the RGB video resolution in the NTU dataset is relatively high, so we are not directly to resize the image from the original resolution to 320x240, but first crop the object-centered ROI area (640x480), and then resize it to 320x240 for training and testing.

2. Methodology

We propose to decouple and recouple spatiotemporal representation for RGB-D-based motion recognition. The Figure in the first line illustrates the proposed multi-modal spatiotemporal representation learning framework. The RGB-D-based motion recognition can be described as spatiotemporal information decoupling modeling, compact representation recoupling learning, and cross-modal representation interactive learning. The Figure in the second line shows the process of decoupling and recoupling saptiotemporal representation of a unimodal data.

3. Train and Evaluate

All of our models are pre-trained on the 20BN Jester V1 dataset and the pretrained model can be download here. Before cross-modal representation interactive learning, we first separately perform unimodal representation learning on RGB and depth data modalities.

Unimodal Training

Take training an RGB model with 8 GPUs on the NTU-RGBD dataset as an example, some basic configuration:

  dataset: NTU

  temp: [ 0.04, 0.07 ]              # Temperature parameter follows a cosine schedule from 0.04 to 0.07 during the training.

  SEHeads: 1                        # Number of heads used in RCM module.
  N: 6                              # Number of Transformer blochs configured for each sub-branch.

dataset:
  type: M                           # M: RGB modality, K: Depth modality.
  flip: 0.5                         # Horizontal flip.
  rotated: 0.5                      # Horizontal rotation
  angle: (-10, 10)                  # Rotation angle

  resize: (320, 240)                # The input is spatially resized to 320x240 for NTU dataset.
  crop_size: 224
