The computer vision has been experienced a rapid development science the 70s of 20 century, especially in the 21st century, with the continuous improvement of computer performance and low-cost digital image capture technology. 从上世纪70年代以来,计算机视觉一直处于飞速发展之中,特别是在进入21世纪以后,随着计算机性能的不断提升和数字图像获取的廉价化,这一领域的发展尤为迅速。
Secondly, the paper analyzes current situation and trend of digital image capture and processing technology, adopts the digital image process system based on TI DSP. 概述了国内外关于自动检测技术现状,分析了数字图像采集和处理技术现状和趋势,采用了基于TIDSP的数字图像采集和处理系统。
The chapter ⅰ briefly described the situation and development trend of the oscilloscope; The chapter ⅱ discussed the plan of high-speed waveform capture technology of digital phosphor oscilloscope; The method of high-speed waveform capture technology is described from chapter ⅲ to chapter ⅴ. 第一章简要介绍了示波器的现状和发展趋势;第二章论述了数字荧光示波器波形高速捕获技术的实现方案;第三章到第五章论述了波形高速捕获的实现方法。
For this reason, It meet market needs to develop the cost-effective Digital Oscilloscopes with fast waveform capture rate and fluorescent waveforms. This paper proposed a target of high-speed oscilloscope waveform capture technology. 开发一种具有较快波形捕获率、能够获得荧光显示效果波形图的高性价比数字示波器符合市场的需要。论文论述了一种示波器波形高速捕获与存储的设计实现。
Digital image is main content of multimedia, and its capture, modification and transmission become more and more easy. The authentication, integrity verification of digital images and the argument of copyright restrict the development of information technology in a certain extent. 数字图像,作为多媒体形式的主要内容,其获取、修改、传输越来越容易,随之而来的数字图像的真实性、完整性验证以及数字版权带来的归属确认等问题一定程度上制约了信息化技术的发展。
