In this paper, we propose a quality metric for video transmitted over HTTP adaptive streaming (HAS). Perceived video quality in HAS strongly depends on the employed rate adaptation mechanisms, transmission conditions and buffer filling levels. Predic

A 3D human head scan contains both texture and mesh data to convey the illusion of a human head. We perform subjective tests with a set of observers to distil the relative importance of texture resolution versus mesh resolution for human head scans,

Off-line scanning, coding, transmission and remote animation of the human affect represents a possible processing pipeline for providing 3D immersion in virtual worlds. In this paper we target applications that make use of compact and scalable 3D rep

The locations of the exchangeable cations of partially La-exchanged NaY zeolites (Si/Al = 2.29) in dehydrated and rehydrated states have been determined using powder X-ray diffraction and 129Xe NMR and from the isotherm of adsorbed xenon.Most the La3

HTTP adaptive streaming (HAS) is based on transmission of independently decodable segments of a video sequence. In this paper, we investigate the coding cost of segmentation in H.264/AVC coded videos and present an optimized segmentation framework. T

This paper proposes a global rate control scheme to maximize the overall encoding quality of a video composition when operating under total bandwidth constraints. The input video sources are encoded based on HEVC. The rate-distortion function for eac

In this paper, two systems for low-complexity MPEG-2 to H.264 transcoding are presented. Both approaches reuse the MPEG-2 motion information in order to avoid computationally expensive H.264 motion estimation. In the first approach, inter- and intra-
