In this paper we propose a new method for video resolution enhancement from compressed video data. Novelty of the approach is that resolution enhancement is done by interpolating the motion vectors. Proposed method works very well for different compression methodologies. We first discuss zooming, when the video is compressed using the Discrete Cosine Transform Domain (DCT). Next we use the Disc...

The paper presents the methodology for 3D video subjective quality evaluation. Described methodology was designed to compare different 3D video compression technologies without an influence of any particular displaying or rendering technology. In addition detailed step by step description of test session design and preparation is provided. Experimental results for state-of-the-art 3D encoders a...

The ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG) formed, in December 2001, the Joint Video Team (JVT) with the purpose to develop a new video coding standard that it is usually known as H.264/AVC, H.264 for ITU-T and Advanced Video Coding (AVC) for MPEG. The main objective was to achieve at least the double of the coding compression, for the same v...

In the 3D video system including depth information, once a depth video is coded by the state-of-the-art video compression tools such as H.264/AVC, depth errors around the boundaries of objects can be intensified, and these can significantly affect the quality of rendered virtual view later. Despite this drawback of depth video coding, its compression is essential because of the enormous amount ...

Editing surgical videos requires a basic understanding of key technical issues, especially when transforming from analog to digital media. These issues include an understanding of compression-decompression (eg, MPEGs), generation quality loss, video formats, and compression ratios. We introduce basic terminology and concepts related to analog and digital video, emphasizing the process of conver...

High Efficiency Video Coding (HEVC/H265) is the most contemporary video compression standard, jointly developed by ITU-T VCEG and ISO/IEC MPEG standard bodies. HEVC, successor of H.264/AVC, is targeted to achieve half the bit-rate compared to its predecessor for the same video quality. Along with primary goal of achieving higher compression and accommodating support for higher resolutions like ...

This paper presents a proposal for a novel video coding scheme intended to encode human faces in video sequences at very high compression using a recognition and reconstruction approach. The scheme is based on the well-known eigenspace concepts used in face recognition systems, which have been modified to cope with the video compression application. An adaptive mechanism is presented to update ...

The predictive coding of video typically entails a motion estimation and compensation step followed by lossy encoding of the residual between the original and predicted images. While this strategy has been shown to be effective for moderate to high rate video compression applications (e.g., the MPEG-1 video coding standard [1]), it neglects the fact that significant correlation may exist betwee...

MPEG-4 video has been designed as a standard for video and audio compression, content-based functionalities, scalability of texture, images and video, shape coding, robustness in error-prone environment, and face and body animation. With all these functionalities, however, MPEG-4 still has limitations in practical software development. In this paper, we developed the frame preprocessing for rea...

Video streaming, or the real-time delivery of video over a data network, is the underlying technology behind many applications including video conferencing, video-on-demand, and the delivery of educational and entertainment content. In many applications, particularly ones involving entertainment content, security issues, such as conditional access and copy protection must be addressed. To resol...
