Abstract

A method of operating an activity recognition system 24 includes capturing ambient radio frequency (RF) data 40 by an RF sniffer 36. The ambient RF data 40 is then received by a processor 50. The processor 50 reduces noise content of the ambient RF data 40. Background is then subtracted from the ambient RF data 40 by the processor 50. The processed ambient RF data 40 is then converted into an image 60 by the processor 50. The system generates successive images 60 for each one of a plurality of time intervals. An image processing algorithm 62, stored in a storage medium 52 and executed by the processor 50, is applied to the plurality of successive images 60 to determine activity recognition.
