First, in order to verify the correct of this retrieval month, by using the data of three-dimensional wind field, raininess field and temperature field that are output by MM5 numerical simulation, we climate the radial velocity field and echo intention field in the in-phase observation area of Dual-Doppler radar, then, on the base of the upwards retrieval theory and using the radial velocity field and echo intention field in the in-phase observation area of Dual-Doppler radar, we retrieve the atmospheric three-dimensional wind field.

首先，为检验此种反演方法的可靠性，我们使用MM5数值模式输出的三维风场、雨强场、温度场等数据，分别模拟生成两部雷达同步观测区的径向速度场和回波强度场，然后根据以上的反演理论利用模拟的双多普勒天气雷达观测到的径向速度场和回波强度场反演出大气三维风场。

We experimentally evaluate the effect of the proposed method using our emotion retrieval algorithm and random algorithm. Four kinds of emotion images, thick fashion images, succinct fashion images, passional scenery images and wide view scenery images are retrieved and compared. The experimental results show that our retrieval algorithm is better than random algorithm.

The whole retrieval process was composed of random segment retrieval and total matching: the first was to select a segment from template model as object to retrieve in stored signal and the second was to judge whether the potential object signal was the template model based on random segment.

把整个检索过程分成随机段检索和整体匹配两个阶段：随机段检索是从参考模板中随机选择一段作为检索目标进行检索；整体匹配是在随机段检索出的基础上，判断潜在目标信号是否为参考模板。

In this scheme, PICF based on higher order statistics is firstly extracted in the reduced space for effective representation of face images, and a PICF-based similarity measurement is proposed in the face image retrieval stage to ensure the efficiency of computation and the accuracy of retrieval and to eliminate the ambiguity in the order of independent features.

为确保计算有效性和检索正确率，在图像检索阶段提出一种基于PICF方法的相似性测度，可消除独立特征顺序的不确定性。

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.
