Description: Nicewords-Dzend版
Nicewords是由工作在顶级门户网站的几名资深高级工程师利用爬虫技术(蜘蛛机器人,spider)、分词技术和网页萃取技术，结合白帽SEO(规避了一切风险的搜索引擎优化)，利用URL重写技术、缓存技术，使用PHP语言开发的一套能根据设置的关键词自动抓取互联网上的相关信息、自动更新的WEB智能建站系统。利用NiceWords智能建站系统，只需要在配置页面上设置几个关键词，NiceWords就能全自动的生成一套能自动更新的网站了。 您要做的仅仅是设置几个关键词，其他的一切交给NiceWords来完成-Nicewords-Dzend version Nicewords by working in several top-level portal, senior engineer using reptiles technology (robot spider, spider), sub-word extraction technology and web technology, combined with white hat SEO (to circumvent all the risk of search engine optimization ), the use of URL rewriting technology, caching technology, the use of PHP to develop a set of language according to settings automatically crawl Keywords relevant information on the Internet, automatic update system WEB Intelligent建站.建站use NiceWords intelligent systems, only need to configure the settings page a few words, NiceWords will be able to generate a set of fully automated web site to automatically update the.

Description: 状是含有高层语义信息的视觉特征，在基于内容的图像检索及图像识别中具有重要的应用价值。有很多种描述子可以描述图像的形状特征，傅立叶描述子可以把二维的图像轮廓信息简化成一维问题进行处理，应用非常广泛。然而自然图像的形状特征通常是杂乱的，有噪声的，提出了一种图像预处理方法，得到净化的形状图像，通过实验研究傅立叶描述子算法提取形状特征的效果。-Abstract Shape is a visual feature which contains intrinsic high-level semantics, and has a great application value in CBIR(Content-Based Image Retrieval) and IR(Image Recognition). There are many descriptors for shape feature. Fourier descriptor predigests 2-demensional image information to 1-demensional signal and be used widely. In fact, the shape of natural image is often messy and noisy. So, this paper proposes a preprocessing method which can clean the noisy shape image, and then researches and analyses the shape feature extraction with Fourier descriptor method with an experiment.
