Toward the Unaided Estimation of Human Walking Speed Based on Sparse Modeling.

The ability to track people's movement (e.g., the human walking) is an important topic of interest in numerous research areas. State-of-the-art systems based on, e.g., dead reckoning, usually do not need any additional infrastructure. The disadvantage of the method is the poor accuracy because of measurement noises. The typical approach to noise cancellation is zero-velocity update (ZUPT). The met...
