gaitutils library

Useful code to generate and manipulate data for gait recognition.

In particular, this library offers the following functionality:

  • Person detection and tracking in videos.
  • Optical flow computation.
  • Generation of person-centric optical flow samples. Ready to be used with OF-based CNNs for gait recognition.

Demo code at Google Colab

1) People detection and tracking

Use the following Google Colab: Google Colab

2) Optical flow computation

Use the following Google Colab: Google Colab

3) Generate OF-based samples for gait recognition

This step has to be performed after 1 and 2.

You can use the latest section of the previous Colab (in step 2) to generate the actual input samples for the CNN.
