WiFi Action Recognition via Vision based Methods

Abstract: 

Action recognition via WiFi has caught intense attention recently because of its ubiquity, low cost, and privacy- preserving. Observing Channel State Information (CSI, a fine-grained information computed from the received WiFi signal) resemblance to texture, we transform the received CSI into images, extract features with vision-based methods and train SVM classifiers for action recognition. Our experiments show that regarding CSI as images achieves an accuracy above 85%. Our contributions include:
• To our best knowledge,we are the first to investigate the feasibility of processing CSI by vision-based methods with extendable learning-based framework.
• We regard CSI of each Tx-Rx pair as a channel and investigate early and late fusion of multi-channels.
• We could know where and what action user performs with location-awareness classification.
