based on the analysis of video retrieval issues among different time scales, such as retrieval between reedit video or original video and different frame rate videos,this paper proposed a novel dynamic time warping optimal matching algorithm.

摘 要：针对不同时间尺度视频间的匹配问题，如人为再编辑视频与原始视频间的匹配以及不同帧率视频间的检索等，提出了一种基于动态时间规划的最优匹配算法。

This paper studies the concrete implementation flow of contour-based retrieval based on wavelet transform modulus maxima , multi-scale morphology and invariant relative moments. Also, experimental results are given to validate the feasibility of our strategy and the corresponding retrieval performance is analyzed.

从理论和技术的角度研究了在基于目标形状的遥感影像检索中，应用基于小波变换模极大值和多尺度形态学的边缘检测方法以及基于不变相对矩的轮廓特征描述方法的具体实现技术流程，通过实验充分验证了本文方法的可行性，并分析了检索性能。

By adjusting the weights of the two classes in image retrieval, we can get different results which depend on our interest in local or global similarity. Wavelet-based salient point has been used for image retrieval.

在图像检索时，通过对这两类图像块分别进行相似性度量，对得到的结果加以不同的权重，以实现对图像局部或全局不同要求的检索。

Sarcomere is distributed information retrieval software based on the Grid Information Retrieval GIR proposed standard .

是一个分布式的基于网格信息检索的信息检索软件。

Latent semantic index LSIis a new algebraic model for information retrieval, which maps documents and queries vectors into a lower dimensional space by singular value decomposition, so that the inherent vagueness associated with a retrieval process based on keyword sets is considerably reduced and semantic association among the documents is highlighted consequently.

隐含语义索引是一种新型的信息检索模型，它通过奇异值分解，将词向量和文档向量投影到一个低雏空间，消减了词和文档之间的语义模糊度，使得文档之间的语义关系更为明晰。

Under all kinds of fuzzy conditions,fuzzy message retrieval is implemented really. Object field skew is discussed and processed for fuzzy retrieval of Chinese message,and chief p...

We construct the synthesis reasoning sources according to the multimedia object low-level features and the reasoning source intensity field according to the multimedia co-existence information. A series of multimedia semantic spaces are built by spectral method after synthesis reasoning. The cross-media retrieval is performed on a per-query basis by which different retrieval methods are adopted for different queries.

首先根据多媒体对象的底层特征构造推理源，根据多媒体对象的共生关系构造影响源场来进行综合推理，并构造出多媒体语义空间；然后针对不同检索例子，根据伪相关反馈为每一个检索例子自适应地选择不同的检索方法进行跨媒体检索。

We are forbidden from giving money to these shoeless, skinny children, as this will perpetuate begging.

向光着脚，骨瘦如柴的孩子施舍是不可以的，因为要招来无休无止的乞讨。

It would be hard not to fall victim to some sharpeyed policeman.
