One of the main obstacles that impede further expansion of Tor, the most popular anonymous communication system, is its large performance variance. The problem becomes worse when bandwidth-intensive applications, such as video streaming, contend with latency-sensitive applications, such as web browsing, for the scarce resources. Most of the existing solutions involve circuit-scheduling techniques...
Video caption extraction has become a very popular research area in the last few decades. Many reasons makes it a challenging task. A large number of techniques have been proposed to address this problem. This paper reviews the progress in this area and various methods towards different stages of text extraction in videos, and also discusses the promising direction of the future research.
HyperText Markup Language (HTML) is the main markup language for web pages. HTML5 is a new generation of HTML standards. With the development of HTML5, it has wide range of applications in the multimedia direction. This new standard first describes the Video and Audio tag, and then elements of Video and Audio are discussed, pointing out that the support of the current browser to Video and Audio format...
In this paper, we propose and implement a novel method for recognition static hand gestures using depth data from Kinect sensor of Microsoft. Compared to the entire human body, the hand is a smaller object with more complex articulations and more easily affected by segmentation errors. So it is a very challenging problem to recognize hand gestures. Our approach involves choosing HOG feature with both...
In this paper, we propose a new video encoding strategy â" Video description length guided Constant Quality video coding with Bitrate Constraint (V-CQBC), for large scale video transcoding systems of video charing websites with varying unknown video contents. It provides smooth quality and saves bitrate and computation for transcoding millions of videos in both real time and batch...
Peer-to-Peer (P2P) media streaming networks have attracted significant research interest recently. However, it is challenging to design live P2P media streaming systems because of the stringent time constraints on the delivered media streams, which require more efficient and resilient overlay. In this paper, we focus on live P2P media streaming networks, a promising application flourishing in the...
In this paper, the transmission distortion introduced in the coded multi-view video stream is analyzed by mathematical method. This model takes into account the interdependent coding among views, which is an important component of multi-view video coding. The model can be used for any multi-view video coding scheme that uses motion compensation and disparity compensation, transform coding and entropy...
This paper analyzes the distortion in decoded multi-view video caused by random packet losses in the underlying transmission network and proposes an error concealment method for for multi-view video. Taking into account the interdependent coding among views, which is an important component of multi-view video coding, a distortion estimation formula is developed by mathematical discursion. Additionally,...
In this paper, a real-time high-resolution multi-view video transport system which can deliver multi-view video over IP networks is proposed. Video streams are encoded with H.264/AVS. Owing to the massive amount of data involved, multi-view video is delivered in two separate IP channels. Since packets losses always occur in IP networks, a novel packets processing method is employed in the proposed...
This paper researches about an intelligent surveillance system, which is used for surveiling separated-moved and important remote-object. This system is based on WLAN, which followed the IEEE 802.11b/g and could communicate smoothly with Ethernet or Internet etc. For an intelligent video encoder, we used an efficient video coding algorithm based on SPIHT (set partition in hierarchical trees), which...
