Shrinkage estimation of high dimensional covariance matrices
We address covariance estimation under mean-squared loss in the Gaussian setting. Specifically, we consider shrinkage methods which are suitable for high dimensional problems wit...

Postural time-series analysis using Empirical Mode Decomposition and second-order difference plots
This paper presents a new method for analysis of center of pressure (COP) signals using Empirical Mode Decomposition (EMD). The EMD decomposes a COP signal into a finite set of b...

On the error analysis of vertical line pair-based monocular visual odometry in urban area
Abstract— When a robot travels in urban area, Global Positional System (GPS) signals might be obstructed by buildings. Hence visual odometry is a choice. We notice that the verti...
