In view of the increasing demand of recognition system for paper currency number, to develop a type of number recognition system based on CIS and DSP. The hardware is composed of CIS and DSP which control image acquisition and process. The software is composed of image acquisition, character correction and recognition. To recognize character with noise pollution rapidly and accurately, a novel approach...
Electronic Program Guide (EPG) is a feature where the program schedule of the channel is shown as a blended text over the video of the channel user is viewing. In case of STB the hardware is aware of which channel it is tuned to and so its possible to show EPG information easily. But in India where, still 93% of total TV viewers are watching TV from Radio Frequency fed cable, it becomes a challenge...
Scintillation noise artifacts are a part of intensified imagery for both analog and digital sensors. The high intensity flashes are similar to classic “salt” noise although they often are multiple pixels in extent; they can prove very distracting when utilizing intensified imagery under stressful conditions. In stereo intensified vision system, the fact that artifacts occur at different locations...
Based on the group of SONY Company ICX229AK PAL image sensor chipset, PAL integrative camera with VGA interface is designed in this paper. Using the DSP + FPGA + ASIC architecture, it completes the acquisition of the video signal and display, and achieves key technologies of auto-focusing and auto iris in the FPGA. Some new type practical functions such as four images storage, mouse driver, real-time...
This paper proposes a system of video display and capture. The advantage of this platform is miniaturization, and the size is just as big as a 2.8 inch LCD screen. The hardware platform mainly consists of a DSP and other ICs such as video AD, video DA and LCD control chips. We get video data from a camera and show it on a video display and a LCD screen. The same time system implements digital zoom...
The next generation of Earth-observing spacecraft are likely to generate enormous volumes of data. A major challenge lies in the conversion of these mountains of data into information useful to researchers and other users. Hierarchical segmentation is one way to detect relationships among regions in a hyperspectral image. We implemented this algorithm on a next-generation space-capable hardware platform,...
Xilinx and Mathworks jointly proposed System Generator (SysGen) and Simulink to accelerate development of DSP (digital signal processing) style applications on Field Programmable Gate Array (FPGA) chips. However, most of developments with Simulink and SysGen end at simulation stage without complete stand-alone implementation on FPGA since these tools do not come up with sufficient IO system libraries...
A novel approach for counting people passing through a region where is surveilled by a parallel-fixed binocular camera is proposed in this paper. Firstly, two virtual counting lines are set to obtain four line space-time gray images. Then an integrated algorithm based on binocular stereovision and regional gray projection is proposed to extract and split overlapped moving objects in complex counting...
In this paper, a novel approach for defects detection in web inspection based on TMS320DM642 DSP development board is proposed. The whole commercial web inspection system can be divided into three major function units: image capture, real-time processing of line-scanned images and the networking transmission. An innovative line-analysis based threshold detection algorithm is presented. The experimental...
As the LHC luminosity is ramped up to the design level of 1034 cm-2s-1 and beyond, the high rates, multiplicities, and energies of particles seen by the detectors will pose a unique challenge. Only a tiny fraction of the produced collisions can be stored on tape and immense real-time data reduction is needed. An effective trigger system must maintain high trigger efficiencies for the physics we are...
Real time image analysis has undergone a rapid development in the last few years, due to the increasing availability of low cost computational power. However computing power is still a limit for some high quality applications. Highresolution medical image processing, for example, are strongly demanding for both memory (~250 MB) and computational capabilities allowing for 3D processing in affordable...
The increasing amount of data produced in satellites poses a downlink communication problem due to the limited data rate of the downlink. This bottleneck is solved by introducing more and more processing power on-board to compress data to a satisfiable rate. This paper introduces an algorithm which has been developed to compress hyperspectral images at low complexity and describes its mapping to a...
A hardware flatform detecting and sorting the faults of cigarette package is designed by using the technology of machine vision. Algorithm and systemic software are also designed according to its characteristics. With stability and accuracy it is of some guiding value to the high speed on-line package detection.
High speed image and video processing is becoming increasingly important in many applications, especially in robotics. A high speed vision system involves grabbing image frames from a single or multiple sensors and processing of the data in a limited time. Therefore, the requirement of real-time processing of the images is the key problem in dealing with such applications. Moreover, to obtain the...
This paper proposes a CDFG (control data flow graph) generating method from a C program for LSI design. At first, an application program described in C language is analyzed. And a hierarchical CDFG that maintains the program structure for optimal HW assignment is generated. After a generation of the CDFG, every operation in the CDFG is partitioned to data operation or address operation for design...
With the growing number of video content analysis applications, efficient implementation has become increasingly important. Video-object tracking using image moments is an important subtask in video-content analysis content algorithms. In this paper, we will present a method of accelerating the computation of geometrical moments and the resulting moment engine to a throughput of 130-fps. Furthermore,...
