DIGITAL IMAGERY is pervasive in our world today. Consequently, standards for the efficient representation and interchange of digital images are essential. To date, some of the most successful still image compression standards have resulted from the ongoing work of the Joint Photographic Experts Group (JPEG). This group operates under the auspices of Joint Technical Committee 1, Subcommittee 29, Working Group 1 (JTC 1/SC 29/WG 1), a collaborative effort between the International Organization for Standardization (ISO) and International Telecommunication Union Standardization Sector (ITUT). Both the JPEG [1–3] and JPEG-LS [4–6] standards were born from the work of the JPEG committee. For the last few years, the JPEG committee has been working towards the establishment of a new standard known as JPEG 2000 (i.e., ISO/IEC 15444). The fruits of these labors are now coming to bear, as JPEG-2000 Part 1 (i.e., ISO/IEC 15444-1 [7]) has recently been approved as a new international standard.

本驱动程序在linux2.6.17中测试通过。yangxing msn:lelma_yx@hotmail.com 希望对SPI操作的朋友有所帮助。 一、工作方式: 从设备:SPI为MASTER模式 S3C2410:SPI为SLAVE模式+DMA 二、工作流程 1.S3C2410从接收:当从设备发送数据时,S3C2410利用DMA方式收数,收到指定长度的数据,则进入DMA中断,将接收的数据拷出。 2.S3C2410从发送:当S3C2410需要发送,首先由RTS请求发送,然后等待从设备应答CTS,当从设备应答CTS时,进入外部中断,启动DMA发送,发送完成,再次进入从接收状态。 三、文件位置 spi_dma_slave.c spi_dma_slave.h circular_buf.c circular_buf.h 等文件存放入driver/char/目录 dma.c存放于arch/arm/mach-s3c2410/目录 dma.h存放于include/arm-asm/mach-s3c2410/目录 四、使用环境 1.arm-linux-gcc-3.4.1

MFC应用程序中的状态条可以很方便的显示应用程序的状态,有 时需要用Bitmap位图显示程序状态,但是MFC的CStatusBar类只直接支持显 示文本,并不支持图形。本文以实例说明了如何在状态条中加入Bitmap位图。 本文内容适用于Microsoft Visual C++ 1.0/2.0/2.1/2.2/4.0/4.1所包含的 Microsoft Foundation Classes(MFC

在pc 机的根目录下建立minigui- free 目录,将下载的源代码包copy 到该目录, 解压缩,生成libminigui-1.3.3、minigui-res-1.3.3、mde-1.3.0、mg-samples-1.3.1。 我在该目录中建立nfsroot 目录,用以存放生成的文件。

Box-Muller变换,将[0,1]均匀分布转换为[0,1]高斯正态分布,在matlab中也可用randn函数生成正态分布。变换的思想可用于其他没有正态分布随机函数的编程语言(如C)

一般来说,任何大于0的正整数n的阶乘等于n与(n-1)的阶乘的积,即n!=n(n-1)!。用(n-1)!的值来表示n!的值其表达式就是一种递归调用,因为一个阶乘的值是以另一个阶乘的值为基础的。 此程序是采用递归调用求正数n的阶乘的程序

The XML Toolbox converts MATLAB data types (such as double, char, struct, complex, sparse, logical) of any level of nesting to XML format and vice versa. For example, >> project.name = MyProject >> project.id = 1234 >> project.param.a = 3.1415 >> project.param.b = 42 becomes with str=xml_format(project, off ) "<project> <name>MyProject</name> <id>1234</id> <param> <a>3.1415</a> <b>42</b> </param> </project>" On the other hand, if an XML string XStr is given, this can be converted easily to a MATLAB data type or structure V with the command V=xml_parse(XStr).
