Gait Based User Recognition from Channel State Information(CSI) collected from WiFi Data

Deep learning methods for user recognition from Channel State Information(CSI) collected from WiFi Data. We used Intel CSI Tool and Atheros CSI Tool to collect our gait dataset(private). The methods in this repo convert CSI data to spectrograms and use deep learning methods for user recognition. Refer to the publications listed below for further details of the method.

Directory Structure

• models/: Deep learning models/experiments
• preprocessing/: Scripts used to preprocess the CSI data
• theoretical_derivation/: Theoretical derivation of the expected spectrograms from human gait
• tools/: Arbitrary tools to plot results/spectrograms, debug CSI tool
