The main results in this paper as follows: First, a prototype of a shape-based image database retrieval system is completed, it can receive the query mode both by giving an example image and by sketching the desired object on the screen, Second, five shape-based image retrieval methods are realized; Third, an algorithm based on triangulation for shape-based image retrieval is brought forward. In this algorithm, firstly, the edge of the original image is followed and the candidate corners in the original image are detected. Then the counterpoints of the candidate corners in the result of edge follow are found, and the boundary corners whose counterpoints have been found are queued in the order of their counterpoints in edge follow. After these steps, the boundary corners are triangulated and triangles are obtained which can show the true shape of the original image. Finally, shape feature is obtained by calculating the angle histogram of the triangles.

同时本文中主要完成了以下三方面的工作：完成了一个基于形状特征的图象检索的原型系统，可实现例子图象或徒手绘草图两种查询方式；实现了五种利用形状特征进行图象检索的具体方法，并对其进行了分析比较；并且在继承将三角剖分引入形状检索的思想基础上提出了利用三角剖分进行形状检索的一种新算法：先对原图象进行边界跟踪和角点检测；然后寻找初始角点在边界跟踪中的对应点，并对找到对应点的角点按其对应点在边界跟踪中的顺序进行排序；再对排序后的角点进行德洛内三角剖分，得到能表示目标真实形状的三角形序列；最后计算三角形序列的角度直方图作为形状特征，并进行相似性匹配。

Re-vectorization is performed on the basis of original vectorization by obtaining the initial parameters such as line types and slope. Inuring tricing it can adjustthe parameter adaptively. To decrease the influence of noise pixels, we designed a stop probe to detect tracing-stop conditions. Process of re-vectorization is performed recursively until quality of graph entity is satisfactory.Finally, some key technologies for 2D graphs reconstruction are studied. The issues concerned include the recognition and presentation of topologic relations among graphs entities and a directed and weighted graph model established to describe the relations and techniques on dimension driven.

在获得对图素识别质量的评价之后，质量较差的图素被输入到错误自动校正器进行错误校正处理，本文提出&二次矢量化&的错误校正思想，二次矢量化是在初步矢量化所获得知识的基础之上，取得初始参数，并在跟踪过程中动态校正参数，在跟踪结束时引入跟踪终止检测探针以消除光栅图像中黑白噪音的影响，使得算法具有较强的抗噪音干扰能力，校正后的图素仍需进行质量评价，未能通过评价的图素需递归执行二次矢量化算法。

One is that the computer model of microvascular network is founded and the growing of the network is simulated. Another is that some new effective methods of digital picture processing for microvascular network images are studied, and then the images got from mouse mesenteries experiment are processed with these new methods.

Motivated by these researches, the thesis proposes an original paradigm that implements IBMR in wavelet domain. In general, IBMR means performing a set of operations in image space, such as warping, correspondence searching, mosaicking, interpolation, and so on.

通常意义下的IBMR是在图象空间中完成一系列的变换、对应匹配、拼合、插值等操作，这些操作的复杂度不仅跟图象分辨率有关，往往还与计算象素的邻域大小、图象中的特征多少、参考图象的多少等因素有关。

Excel can not only protracts coordinate according to the data you input, but also display many charts, contrasts them, creates transparent charts and so on.

平时大家接触到 excel ，可能只是拿它编辑几个表格，然而，真正让 excel 有其用武之地的却是统计图。excel 不仅能够根据你所输入的数据组绘制坐标图，还可以同时显示多份图表，进行多图对比，生成透明图表，以及生成立体运动的曲面图。

In order to conserve raw materials, reduce costs, at the time of the first three days of mathematical seihan "the regeneration of positive PS plates, each 印张 essentiallythe with a overprinter version is enough (with the exception of special circumstances), and the eye for an eye" on the selection of mathematics is a new version of positive YP-IIPS, as a result, with positive YP-IIPS Edition plates made of plates might as well have ratooning positive PS Edition plates.

为了耗费原质料、贬低本钱，制版时《初三数教上》采取了复活阳图PS版，根基上是每个印张用一套印版不离不足了，而《月朔数教上》采取的是陈的阳图YP-IIPS版，甘休，用阳图YP-IIPS版制成的印版的耐印力还不如复活阳图PS版的耐印力。
