We address the problem of gait-based people identification by using two main approaches: from 2D information, and from 3D information. Moreover, we have created a new multi-view gait database which contains gait sequences of 20 actors that depict ten different trajectories each, including curved paths.
Gait recognition from 2D information.
From sequences of RGB data, we extract short-term dense trajectories that are described with the Divergence-Curl-Shear (DCS) descriptor. Then, the Pyramidal Fisher Motion (PFM) descriptor is computed to obtain a video-level gait descriptor.
The following publications present our results by using as basis the previously explained approach:

Gait recognition from 3D information.
These approaches require multiple camera viewpoints to obtain 3D information of the target person. Then, different descriptors are proposed in the following publications:

To test some of our approaches, we have created a new multi-view gait database which contains gait sequences of 20 actors that depict ten different trajectories each, including curved paths. This database has been specifically designed to test Gait Recognition algorithms based on 3D data. Thus, the cameras have been calibrated and methods based on 3D reconstructions can use this dataset to test. Binary silhouettes are also provided.
