When facing the emergencies, to achieve the whole day real-time scanning services on targets, we propose a program with integration of visible and infrared imagers. A novel airborne low-altitude monitoring system is designed. it helps operators to detect targets accurately. Experiments show that the design is feasible and the system is practical, reliable, and easy to operate, displays Chinese characters,...
The field of object searching and recognition systems is an increasingly popular area of focus for industry and research labs alike. Object searching mechanism is a challenging task. The proposed system makes use of computer vision techniques. Real time object search poses many difficulties in recognizing objects. These difficulties can be overcome by Triangular Matrix Search Algorithm and Real Time...
With the development of the wireless communications technology and the multimedia technology, the wireless internet multimedia transport of real-time becomes an important applications field. We will meet a problem that the distinguish of the status of package loss is not very good which will affect the QoS when we transport multimedia data in wireless internet. Based on this problem the article comes...
In this paper we present a novel method for high quality real-time video enhancement; it improves the sharpness and the contrast of video streams, and simultaneously suppresses noise. The method is comprised of three main modules: (1) noise analysis, (2) spatial processing, based on a new multi-scale pseudo-bilateral filter, and (3) temporal processing that includes robust motion detection and recursive...
Augmented reality aims to insert virtual objects in real scenes. In order to obtain a coherent and realistic integration, these objects have to be relighted according to their positions and real light conditions. They also have to deal with occlusion by nearest parts of the real scene. To achieve this, we have to extract photometry and geometry from the real scene. In this paper, we adapt high dynamic...
Received video quality is dependent on the available link rate and the packet loss rate, which are inter-related in a busy network link. Even low packet loss ratios (PLRs) can significantly reduce the video quality. In this paper, a packet level parity FEC is applied to the video stream in order to reduce the video PLR. A constant gross data rate is assumed, such that adding a FEC leads to a decrease...
With recent advances in video encoding and network technology, media streaming services are getting popular. Media streaming system based on the traditional server/client or CDN architecture has a scalability problem, and peer-to-peer media streaming system using resources of peers in the system can provide better scalability. Previous media streaming services are suited to play stored contents such...
Many artists attempt to make art work from famous celebrated picture or old masters. . We attempt to remake them using new digital intaglio for automatic non-photorealistic rendering (NPR), it is introduced in this paper. Usually they implement it using paint brush, or photoshop to analysis the old masters and remake them. It is very normal thing in modern art field . We implement digital algorithm...
The teaching video recording and broadcasting system gathering multimedia data integration with streaming media video recording is designed and developed to solve the problem of streaming video courseware high production cost and low efficiency. With the video recording and screen data acquisition functions, it is an appropriate support tool for teachers to prepare lessons, teaching and classroom...
This paper presents the design and Research of the Streaming Media Video Teaching System. The techniques of multi-media teaching, Computer Assisted Instruction and network are all involved in this system. The teaching environment, teaching resources, teaching content and student information can all be managed through Network Video Teaching System. Teachers can integrate the multi-media elements provided...
In this paper, we introduce an IP multimedia sub-system (IMS) based testbed which provides a platform for the study of real-time services integration and orchestration. This open-source based testbed is built on the principle of service oriented architecture (SOA), with an emphasis for real-time network services. We further developed service-oriented system functionalities such as optical network...
The huge coverage space of IPv6 addresses and providing guaranteed support for the ever increasing customer demand, results in the dealing with bigger packet header-size compared to the payload-size especially in some real time video and audio applications, consequently more bandwidth is wasting. Using the advantages of MPLS with IPv6 is still one of the migration challenges at the backbone. Payload...
A composite algorithm is proposed to identify the opened and shut states of eye in real-time video. Sequentially, each frame of the video is processed first to find and separate the eye regions; then, the accumulation array of circular Hough transform is applied for detecting circles to recognize the opened state of the eye, and the upper eyelid curve is calculated to identify its bending direction...
Growing bandwidth demand in the Internet requires new algorithms and architectures to provide a high degree of QoS. Further, to complicate the problem of Traffic Engineering, real time data processing requires more priority than non-real time data processing. In this paper, we present an effective solution for improving QoS of audio and video packets in MPLS networks under real time traffic conditions...
Providing time-shifting function in real-time streaming is a challenging task. In this paper, we propose J-tree, a novel peer-to-peer real-time streaming model which can provide live and time-shifted streams using dynamic multicast trees. Super peers of dynamic trees are used to access to and distribute time-shifted data. We address the following two key technical issues in J-tree: (1) The establishment...
