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...
As an important field in information security, image encryption algorithm has been a research focus. At the same time there are few works on fractal set as the encryption key among various encryption algorithms. In the paper, Mandelbrot set (abbreviated as M set) and the Hilbert transformation are utilized to generate the random key. Since M set can be iterated from only a few parameters, it can reduce...
Because of the limit of the domestic configuration software which is in the use of scrutinizing the coal mine, the ActiveX technique is discussed and the design of the safety of coal mine, which utilize the ActiveX technique, is actualized. The fig of system frame and the implementation of part of modules are also given. This system can provide the friendly interface for the controlling of coal mine,...
Daily evaluation of the power grid enterprises often involve large amounts of data, and most of the work is tedious, power supply capacity as an important embodiment of corporate responsibility needs good evaluations. We have established a multi date acquisition tool to achieve a large number of data collection, and allow the computer to complete complex calculation, through the various analysis of...
The goal of the blabbering voice-to-Speech Translation research is to enable real-time, interpersonal communication via natural spoken language for people who do not share a common language. The Multilingual Automatic blabbering voice-to-Speech Translator (MASTOR) system is the first Speech-to-Speech system that allows for bidirectional (blabbering voice Tamil) free-form speech input and output. The...
The RIDER -Réseau et Inter connectivité Des Energies classiques et Renouvelables (Network and Inter-Connectivity of Classical and Renewable Energies) project gathers a pool of university laboratories, national and international companies to design intelligent energy management platforms. We present here our contribution on designing data warehouse architectural models for massive and heterogeneous...
Quality of service (QoS) provisioning generally assumes more than one QoS measure which implies that QoS routing can be categorized as an instance of routing subject to multiple constraints: delay-jitter, bandwidth, cost, etc. We study the problem of constructing multicast trees to meet the QoS requirements of real-time interactive applications where it is necessary to provide bounded delays and bounded...
In order to solve the problem that the membership functions of traditional fuzzy control are difficult to be determined, a new method (fuzzy network) of fuzzy control is proposed. Fuzzy network adopted the network structure in which the membership functions, control rules, fuzzy reasoning and defuzzification process are included. Compared with the fuzzy neural network, fuzzy network don't need learning...
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...
In this paper we propose a new algorithm for the least square fitting of ellipses from scattered data. Originally based on the one proposed by Fitzgibbon et Al in 1999, our procedure is able to overcome the numerical instability of that algorithm. We test our approach versus the latter and another approach with different ellipses. Then, we present and discuss our results.
This paper describes an approach to real-time optical flow computation that combines the corner features and pyramid Lucas-Kanade. Corners instead of all the points in the image are taken into optical flow computation, which could reduce the amount of calculation to a large extend. The experiment has shown that using this optical flow algorithm to track targets is effective and could meet the requirements...
There is an emerging focus on real-time data stream analysis on mobile devices. A wide range of data stream processing applications are targeted to run on mobile handheld devices with limited computational capabilities such as patient monitoring, driver monitoring, providing real-time analysis and visualization for emergency and disaster management, real-time optimization for courier pick-up and delivery...
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...
Particle filtering is known as a robust approach for motion tracking by vision, at the cost of heavy computation in a high dimensional pose space. In this work, we describe a number of heuristics that we demonstrate to jointly improve robustness and real-time for motion capture. 3D human motion capture by monocular vision without markers can be achieved in realtime by registering a 3D articulated...
A new floating car data technology in Hefei has been developed that provides real-time traffic information within Hefei's two ring road. It is based on the collection of localisation data, speed, direction of travel and time information from GPS in vehicles that are being driven. The scope of the project is to development and creation of a Web-based data mart for the collection of FCD. The aim of...
This paper describes and deduces the theory of Haar-like features, Integral image and AdaBoost algorithm, which were proposed by Paul Viola, and then researches its improvement. We combine Microsoft Visual C++6.0 with OpenCV Function library to develop the software, and achieve the function of real-time face detection. According to experimental results, we can conclude that the improved algorithm...
Current telepresence systems, while being a great step forward in videoconferencing, still have important points to improve in what eye-contact, gaze and gesture awareness concerns. Many-to-many communications are going to greatly benefit from mature auto-stereoscopic 3D technology; allowing people to engage more natural remote meetings, with proper eye-contact and better spatiality feeling. For this...
In this paper, we present an effective parallel algorithm for polygonizing implicit surfaces. The algorithm can produces triangulation approximation of implicit surface with adaptive size of triangles according to the local curvature of the surface. Our algorithm first divides an given implicit surface into eight parts by subdividing its bounding box. Then, the algorithm finds a seed point for each...
In this paper, we investigate the spectrum scheduling problem for next generation multiband orthogonal frequency division multiplexing (MB-OFDM) ultra-wideband (UWB) systems under QoS and interference constraints. Based on a constrained optimization problem formulation, we propose a cross-layer scheduling solution that takes into account the unlicensed UWB users channel and QoS conditions as well...
