Automatically characterizing places with opportunistic crowdsensing using smartphones
2012
Proceedings of the 2012 ACM Conference on Ubiquitous Computing - UbiComp '12
Preserved Fulltext
CSP combines signals based on location and user trajectories (using WiFi/GPS) along with various visual and audio place "hints" mined from opportunistic sensor data. ...
Place hints include words spoken by people, text written on signs or objects recognized in the environment. ...
This recognition system is based on fully continuous Hidden Markov Models [6] and uses Mel-frequency Cepstral Coefficients [12] (MFCCs) as features. ...
