查询词典 vector basis

Relative to the traditional way of predetermining basis functions, basis functions generated by learning algorithms are adapted to image characteristics and hence more efficient in image representation. Basis function-based image representation is currently a frontier research in the field of image processing, involving multiple disciplines such as statistics, geometry, visual physiology etc.

This theory is discussed in the perspective of its basis, tar get value, theoretical core, methodology frame and theme of critique. Among themthe theoretical basis is analyzed for that the technology is in a dilemma overbeing accepted or being given up as argued in traditional philosophy of technolo gy; the target value refers to human being\'s liberation and the theoretical coreis the rationalization of democracy; the methodology frame is that used to stud y the technology on the basis of social constructivism and the theme of critiqueis farewell to dystopia.

从理论基础、价值目标、理论内核、方法论框架和批判主题等方面对这一理论展开了剖析，其中理论基础是对传统技术哲学&接受还是放弃&技术的两难困境的分析，价值目标是马克思主义的人的解放，理论内核是民主的理性化，使用的是社会建构论研究技术的方法论框架，批判主题是告别敌托邦。

According to international standards, directors and auditors usually have three options with accounts: they can prepare them on a going-concern basis, which is standard but might expose them to charges of negligence if they are wrong; if they do not believe the business is a going concern, they must prepare the accounts on a break-up basis; or they can express some doubts about the company's future, but still prepare the accounts on the going-concern basis.

根据国际准则，主管和审计人员一般来说对账户有3种处理方式：他们可以在持续经营的基础上准备报表——这是标准的，但一旦他们做错了，他们会面临渎职控诉；如果他们不相信企业能继续经营，他们必须在破产的基准上准备报表；抑或他们可以表明其对公司未来的困惑，但仍在持续经营的基础上准备报表。

With the advancement of science and technology, some new theories and new ways emerged gradually, some of them merged with specific theoretical tools, this specific theoretical tools include mathematical morphology, fuzzy techniques, neural networks, wavelet and so on. Secondly, in this paper, it described and analyzed the segmentation method based on the edge in the domain of image segmentation in detail. It did experiments on several edge detection operators using MATLAB, it summarized the advantage and the shortcoming of traditional edge detection operators, and the operating environment. On the basis of the experimental analysis, it implemented an edge location more precise, more efficient operating speed edge extraction method——Template Vector. In this method, it optimized differential approximate calculation of first differential operators the paper mentioned. After experimented on this edge extraction method, contracted with the traditional methods, the edge outline is extracted more accurately and more exquisitely, furthermore, it retained the object outline furthest, and achieved more satisfied edge extraction result.

其次，对图像分割领域中常用的基于边缘的分割方法进行了详细的研究与分析，对各种边缘检测算子进行了MATLAB环境下的实验，分析总结了各种传统边缘检测算子的优缺点和适应环境，并针对传统边缘检测算子在处理显微图像时的缺陷，在实验分析的基础上研究并实现了一种边缘定位更加精确、运算速度更加快捷的边缘提取方法——模板向量算法，在该算法中，对文章提到的一阶微分算子中微分的近似计算作进一步优化，经过对该边缘提取方法进行实验，其结果与传统方法相比，轮廓提取更为精确细腻，且最大程度的保留了图像中物体(目标个体或者明显噪声点)的轮廓，得到了比较理想的边缘提取效果。
