Effective signal denoising methods are essential for science and engineering. In general, denoising algorithms may be either linear or non-linear. Most of the linear ones are unable to remove the noise from the real-world measurements. More suitable

The paper proposes an approach to signal denoising based on a combination of Variational Mode Decomposition with the Split Augmented Lagrangian Shrinkage Algorithm.In our research, we found that the proposed approach gives a great improvement of deno

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 disadvant

The speed of human walking is a valuable indicator of individuals’ health status, for example in sports or medicine. Classic methods such as the camera-based approach have serious limitations: (1) they can be used only in the laboratory setting, an
