Implementation of HMM-Based Human Activity Recognition Using Single Triaxial Accelerometer
Chang Woo Han, Shin Jae Kang, Nam Soo Kim · IEICE Transactions on Fundamentals of Electronics Communications and Computer Sciences · 2010
In this letter, we propose a novel approach to human activity recognition. We present a class of features that are robust to the tilt of the attached sensor module and a state transition model suitable for HMM-based activity recognition. In addition, postprocessing techniques are applied to stabilize the recognition results. The proposed approach shows significant improvements in recognition experiments over a variety of human activity DB.
