The Graphics processors or GPUs have become in a few years powerful tools for applications that require a massively parallel computing. Currently include the applications in multimedia processing, the engineering science and image processing in real time. They offer many advantages such as acceleration of treatment and down energy consumption from an equivalent CPU power. In this paper, we will show...
Human detection is exploited as a key operation in many applications such as automotive safety, intelligent vehicles, assisted living, and video surveillance. Consequently, there is a significant advancement in this area of research in the past years and a vast literature. In this study, the authors propose a pedestrian detection system which relies on sliding covariance matrix feature descriptor...
In this paper, we propose a wormhole router architecture for symmetric 3D-mesh Networks-on-Chip (NoCs) with virtual channels. It uses the credit-based flow control mechanism and dimension-order routing XYZ algorithm. With priority-based scheduling, our 3D on-chip communication model can support the management of different levels of quality-of-service. The router is implemented on FPGA device using...
Detecting pedestrians is a challenging problem owing to the motion of the subjects, the camera and the background and to variations in pose, appearance, clothing, illumination and background clutter. The Region Covariance Matrix (RCM) descriptors show experimentally significantly out-performs existing feature sets for pedestrian detection. In this paper, we present an efficient features extraction...
This paper presents the design and implementation of image processing application on field programmable gate array (FPGA). To improve the implementation time, Xilinx AccelDSP, a software for generating hardware description language (HDL) from a high-level MATLAB description has been used. An FPGA-based architecture for Color Space Conversion has been proposed. The design was implemented on Spartan...
In the programmable device technologies The continuous advancements enable the widespread use of FPGAs in an increasing number of industrial applications. The availability of powerful software design tools is a fundamental requirement to take advantage of the many advanced and specialized resources included in the latest devices. Video acceleration and processing technologies have become critical...
A methodology for implementing real-time DSP applications on a field programmable gate arrays (FPGA) using Xilinx System Generator (XSG) for Matlab is presented in this paper. It presents architecture for Edge Detection using Sobel Filter for image processing using Xilinx System Generator. The design was implemented targeting a Spartan3A DSP 3400 device (XC3SD3400A-4FGG676C) then a Virtex 5 (xc5vlx50-1ff676)...
This paper presents a method for human detection in video sequence. The Histogram of Oriented Gradients (HOG) descriptors show experimentally significantly out-performs existing feature sets for human detection. Because of HOG computation influence on performance, we finally choose a more better HOG descriptor to extract human feature from visible spectrum images based on OpenCv and MS VC++. We realized...
