Gyro-based camera-motion detection in user-generated videos
Bano, Sophia; Cavallaro, Andrea; Llanas Parra, Francesc Xavier (2015)
Conference report
Restricted access - publisher's policyThe paper proposes a gyro-based camera-motion detection method for videos captured with smartphones. First, the delay between the acquisition of video and gyroscope data is estimated using similarities induced by camera ... -
Human activity recognition on smartphones for mobile context awareness
Anguita, Davide; Ghio, Alessandro; Oneto, Luca; Llanas Parra, Francesc Xavier; Reyes Ortiz, Jorge Luis (2012)
Conference lecture
Open AccessActivity-Based Computing [1] aims to capture the state of the user and its environment by exploiting heterogeneous sensors in order to provide adaptation to exogenous computing resources. When these sensors are attached ... -
