This work proposes a novel billing system model for voice call services on cellular networks, which includes the voice quality index estimated on the end user device as an additional parameter in the charging process. The solution proposed is focused on cellular networks, and the main goal is to improve the user's quality of experience (QoE) using the voice call service, because users pay according...
This paper presents a real-time 3D hand posture estimation using the data from a RGB-D camera. A hierarchical method is adopted to first estimate the pose of palm and then the pose of fingers. The particle filtering algorithm with efficient particle generation for tracking the palm and fingers is proposed by analyzing the depth gradient and the contour of hand region. The finger motion model with...
Traditional background modeling methods often require complicated computations and suffer from cavity problems in foreground objects. In this paper, we propose a block-based background modeling method combining multiple detection results derived from color and texture characteristics. This method can significantly alleviate the cavity problem and resist certain shadow interference. Since the proposed...
This paper aims to present a model for an interactive and hybrid digital TV focused on global services and applications framework. The model proposed aims to improve the hybrid broadcast-broadband model with features which run worldwide using a PaaS cloud service, browser applications in a global compliance and second screen scenarios involving pervasive computing. The proposed architecture and a...
