针对嵌入式机器视觉系统向独立化、智能化发展的要求，介绍了一种嵌入式视觉系统--智能相机。基于对智能相机体系结构、组成模块和图像采集、传输和处理技术的分析，对国内外的几款智能相机进行比较。综合技术发展现状，提出基于FPGA+DSP模式的硬件平台，并提出智能相机的发展方向。分析结果表明，该系统设计可以实现脱离PC运行，完成图像获取与分析，并作出相应输出。 Abstract: This paper introduced an embedded vision system-intelligent camera ，which was for embedded machine vision systems to an independent and intelligent development requirements. Intelligent camera architecture， component modules and image acquisition， transmission and processing technology were analyzed. After comparing integrated technology development of several intelligent cameras at home and abroad， the paper proposed the hardware platform based on FPGA+DSP models and made clear direction of development of intelligent cameras. On the analysis of the design， the results indicate that the system can run from the PC independently to complete the image acquisition and analysis and give a corresponding output.

使用Nios II软件构建工具 This chapter describes the Nios® II Software Build Tools (SBT), a set of utilities and scripts that creates and builds embedded C/C++ application projects, user library projects, and board support packages (BSPs). The Nios II SBT supports a repeatable, scriptable, and archivable process for creating your software product. You can invoke the Nios II SBT through either of the following user interfaces: ■ The Eclipse™ GUI ■ The Nios II Command Shell The purpose of this chapter is to make you familiar with the internal functionality of the Nios II SBT, independent of the user interface employed.

基于通用集成运算放大器，利用MASON公式设计了一个多功能二阶通用滤波器，能同时或分别实现低通、高通和带通滤波，也能设计成一个正交振荡器。电路的极点频率和品质因数能够独立、精确地调节。电路使用4个集成运放、2个电容和11个电阻，所有集成运放的反相端虚地。利用计算机仿真电路的通用滤波功能、极点频率和品质因数的独立控制和正交正弦振荡，从而证明该滤波器正确有效。 Abstract: A new multifunctional second-order filter based on OPs was presented by MASON formula. Functions， such as high-pass， band-pass， low-pass filtering， can be realized respectively and simultaneously， and can become a quadrature oscillator by modifying resistance ratio. Its pole angular frequency and quality factor can be tuned accurately and independently. The circuit presented contains four OPs， two capacitors， and eleven resistances， and inverting input of all OPs is virtual ground. Its general filtering， the independent control of pole frequency and quality factor and quadrature sinusoidal oscillation were simulated by computer， and the result shows that the presented circuit is valid and effective.

Contains a complete archiver by Haruhiko Okumura. The archiver uses an LZ engine whose output is compressed with static Huffman. The file is chopped into pieces which all get their own independent set of Huffman tree s. ARJ 2.41, ZIP 2.0 and PKZIP 2.04g use essentially the same method. ZOO and LHA even use excactly the same method.

The GRLIB IP Library is an integrated set of reusable IP cores, designed for system-on-chip (SOC) development. The IP cores are centered around the common on-chip bus, and use a coherent method for simulation and synthesis. The library is vendor independent, with support for different CAD tools and target technologies. A unique plug&play method is used to configure and connect the IP cores without the need to modify any global resources.

ICA can be used in brain activation studies to reduce the number of dimension and filter out independent and interesting activations. This demonstration shows two studies. One provided by Hvidovre Universitets Hospital, Denmark, that consists of fMRI scannings of humans. Another provided by the EU sponsored MAPAWAMO project from fMRI scannings of monkeys. In the demo comparison between icaMS, icaML, icaMF, icaMF (positive sources) and PCA can be made. More detailes can found in [2].

The Molgedey and Schuster decorrelation algorithm, having square mixing matrix and no noise . Truncation is used for the time shifted matrix, and it is forced to be symmetric . The delay Tau is estimated . The number of independent components are calculated using Bayes Information Criterion (BIC), with PCA for dimension reduction.

Although there has been a lot of AVL tree libraries available now, nearly all of them are meant to work in the random access memory(RAM). Some of them do provide some mechanism for dumping the whole tree into a file and loading it back to the memory in order to make data in that tree persistent. It serves well when there s just small amount of data. When the tree is somewhat bigger, the dumping/loading process could take a lengthy time and makes your mission-critical program less efficient. How about an AVL tree that can directly use the disk for data storage ? If there s something like that, we won t need to read through the whole tree in order to pick up just a little bit imformation(a node), but read only the sectors that are neccssary for locating a certain node and the sectors in which that node lies. This is my initial motivation for writing a storage-media independent AVL Tree. However, as you step forth, you would find that it not only works fine with disks but also fine with memorys, too.

很好的linux内核调试软件 兼辕马，没有密码。 The ia64 and ix86 directories contain versions of kdb prior to v2.0 (kdb version v2.0, not the kernel version). Older versions of kdb had complete patches for each architecture it supported, each patch included all the common kdb code. This format was awkward to maintain and use for multiple platforms. Starting with kdb v2.0 there is a common patch against each kernel which contains all the architecture independent code plus separate architecture dependent patches. Either use an old style (v1.8 or v1.9) kdb patch or use a new style (v2.0) common patch plus the corresponding architecture dependent patch.
