TL;DR: A neural network model is proposed to be used to recognize a hand posture in an image using a space discretisation based on face location and body anthropometry.
Abstract: We propose to use a neural network model to recognize a hand posture in an image. Hand gestures are segmented using a space discretisation based on face location and body anthropometry.

TL;DR: In this paper, a method for imparting control to an application program (AP) running on a mobile device is proposed, which comprises the acts of displaying a graphical user interface (GUI) of the AP on a touch panel of the mobile device; capturing a touch input on a portion of the GUI; and monitoring an occurrence of a spatial movement of mobile devices.
Abstract: A method for imparting control to an application program (AP) running on a mobile device, said method comprising the acts of displaying a graphical user interface (GUI) of the AP on a touch panel of the mobile device; capturing a touch input on a portion of the GUI; the method further comprising, when identifying the touch input as a touch input of a predefined first type, the acts of imparting a first AP control associated to the portion of the GUI; monitoring an occurrence of a spatial movement of the mobile device; imparting a second AP control associated to the portion of the GUI in response to the capture of a spatial movement.

TL;DR: The design of both next-generation network (NGN)-based and non-NGN-based architectures that have been recently proposed to enable the deployment of IPTV are presented and the challenges and solutions associated with mobile IPTV and peer-to-peer IPTV systems are described.
Abstract: Internet protocol television (IPTV), a technology that delivers video content over a network that uses the IP networking protocol, has been receiving a lot of attention over the last couple of years. The increasing interest in IPTV is being driven by remarkable advances in digital technologies and consumer electronic devices, broadband networking technologies, Web services, as well as more entertainment demands (enabled by decreasing costs of hardware and software technologies) from both consumers and content providers. In this paper, we briefly discuss IPTV standardization initiatives and present the design of both next-generation network (NGN)-based and non-NGN-based architectures that have been recently proposed to enable the deployment of IPTV. In addition, we describe the challenges and solutions associated with mobile IPTV and peer-to-peer IPTV systems. We Anally present some IPTV trends and identify some of the IPTV challenges that must be addressed to enable the ubiquitous deployment and adoption of IPTV.

TL;DR: It emerges that the cross-correlation coefficients may be quite high when the two stations see the mobile with the same azimuthal angle, and a complete decorrelation is often guaranteed when the mobile is between theTwo stations.
Abstract: Propagation measurements (performed at 900 MHz in a small cell urban environment) and simulations devoted to shadow fading analysis in a diversity context are presented. This work gives a more accurate understanding of the cross-correlation phenomena. It emerges that the cross-correlation coefficients may be quite high when the two stations see the mobile with the same azimuthal angle. In return, a complete decorrelation is often guaranteed when the mobile is between the two stations. The tables derived can be used either to pursue studies about macro-diversity or to investigate further the C/I statistical properties. The realistic model proposed is also of particularly interest in evaluating the performance of handover algorithms and in estimating the macro-diversity gain. For both cases, we present a model of the shadow fading processes, taking into account their different correlation characteristics. We apply this model to perform some simulations.

TL;DR: A new adaptation method consisting in a filter adaptation technique via the maximum likelihood linear regression (MLLR) is presented with an associated filter-adapted training phase to improve separation quality.
Abstract: In this paper, the problem of one microphone source separation applied to singing voice extraction is studied. A probabilistic approach based on Gaussian mixture models (GMM) of the short time spectra of two sources is used. The question of source model adaptation is investigated in order to improve separation quality. A new adaptation method consisting in a filter adaptation technique via the maximum likelihood linear regression (MLLR) is presented with an associated filter-adapted training phase.
