For the non - structured image data , the traditional text - based image retrieval is so inefficient and thereby the content - based image retrieval is bought forward and it has developed a lot 对于非结构化的图像数据,传统的基于文字的检索方法效率很低,为此人们提出了基于内容的图像检索技术,并且取得了一定的进展。
With the difficulty to segment badly - illuminated structured images , we proposed a method based on the characteristic of laser sheet , and also we proposed a method of how to prune the thinning curves with much spikes and branches 最终,我们获得了可用于cad cam的三维数字化数据。本文研究的方法和结论在类似的三维数字化领域也具有普遍的意义。
The model we designed enables users to customize data structure mapping between source database and target database in local machine through getting the structure image of source database and transports it to remote server before converting it to xml formatted which is better for internet transportation 该模型通过获取远程数据库的结构映象,使得用户可以在本地定制源、目标数据库表之间的映射关系。同时,将定制的映射关系转化为适合网络传输的xml格式,输送到远程服务器。
