When high voltage direct current (HVDC) system is under the monopolar operation mode, huge direct current (DC) is injected into the earth through the DC grounding electrode, which will result in earth potential changes in a wide range of area. In this case, DC will be coupled into the nearby alternating current (AC) power grid and have some bad influences, called DC bias phenomenon, on the measuring...
Face recognition is an important technique for Natural User Interface (NUI) and Human Robot Interaction (HRI) and many of the current state-of-the-art face recognition techniques are based on the local features which are extracted from a face alignment method like Constrained Local Model (CLM). But, in a real world environment, face alignment methods often fail to correctly localize the features because...
In this paper we propose a sensor fusion based indoor localization method for mobile Augmented Reality (MAR). The aim of this research is to provide fine-tuning of the line feature based localization to accuracy of centimeter-level by exploring multi-modality of a mobile device. In order to match with line features from the captured scene and the given floor map, a line-based indoor scene analysis...
An avatar is a representation of a real person in a virtual world and a user considers it as his/her secondary personal identity. With the spread of Virtual Reality(VR) technologies, there has been a user's growing interest in how to make an avatar to describe his/her identity well. Recent commercial games also support powerful avatar customization services to satisfy customer's various needs, but...
Feature selection aims to find the most important information from a given set of features. As this task can be seen as an optimization problem, the combinatorial growth of the possible solutions may be in-viable for a exhaustive search. In this paper we propose a new nature-inspired feature selection technique based on the bats behaviour, which has never been applied to this context so far. The wrapper...
