查询词典 shape-shift

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。

The results of UV absorption show that λ max is not sensitive to the electronic effects exerted by the substituent in the coupler moiety. The λ max has a small red-shift when the anilide aromatic ring in the coupler moiety is larger. This indicates that the conjugation effect of the anilide ring with chorosorb is not very significant. It is important to note that a red-shift of 60-130 nm was observed when the coupler component changed from a 2-hydroxy-3-naphthanilide to a 2hydroxy-11H-benzocarbazole-3-naphthanilide coupler. The red-shift may be due to the conjugation resulting from the carbazole ring.

对上述三个系列偶氮染料吸收光谱的研究结果表明，偶合基酰胺芳环共轭环的扩大对偶氮染料在可见光区最大吸收红移作用不是很显著；当偶合基萘环上共轭环扩大了一个咔唑环后，其偶氮染料在可见光区的最大吸收大幅红移，跨入近红外染料行列，这一结果对红外偶氮染料的设计合成具有重要的参照价值。
