A Color Based Image Retrieval Method
一种基于颜色特征的图像检索方法

HUANG Yuan-yuan,HE Yun-feng,<br>元元,
中国图象图形学报 , 2006,
Abstract: By means of self-organizing clustering,a new color-based image retrieval method is proposed in the paper.According to the colors' distributing information in the image,every pixel is assigned a weighing value and thus the initial number of clustering can be confirmed.Therefore,those weighed pixels are clustered and the dominant colors' statistical features are acquired.Based on the dominant colors spread in the image,the colors' moment features are extracted to present their special features simultaneously.Therefore,the whole image's content can be expressed from general statistic to partial distributing by these two kinds of features.The experiments verify the method mentioned above is more efficiently than those ways based on color histogram.
Affective computing and engineering rationality
情感计算与工程理性*

Abstract: Through the compatibility analysis of emotion and rationality, and the study of emotional functions in integration, adaptation, motivity and interaction, it was pointed out that emotion was an effective mechanism in dealing with complex problems in real world. As the emotion functions matched well with the engineering requirements, affective computing, with emotion as its core, was of effectiveness and certain necessity, and had great potential in solving complex engineering problems. Committed the endogenous, relevance and operational strategy of affective computing. Pointed out that concerns should be made to the entry point, the emotion elicitor, the emotion effector, and the platform choice, which constituted the key links to success in emotion-based systems in engineering projects, and gave related recommendations.
Zeuxinella, A Newly Recorded Genus of Orchidaceae from China
中国兰科一新记录属——拟线柱兰属

热带亚热带植物学报 , 2012,
Abstract: Zeuxinella Aver., originally described from northern Vietnam, was recently collected from southwestern Guangxi, China. The genus resembles Zeuxine, but differs in its epichile 3-lobed, with 4 close callosities on the disc, mesachie very short, and rostellum undivided.
STUDIES ON THE CYCLING OF NUTRIENT ELEMENTS IN THE ECOSYSTEM OF THE OIL-TEA CAMELLIA PLANTATION
油茶林生态系统中营养元素循环的研究

Abstract: In the paper the content, net accumulation and cycling of nutrient elements in two oil-tea plantations under the optimization management measures were studied. Taking the oil-tea plantation as on example, the cycle process of nutrient elements in the ecosystem was analysed and some dynamics models of N, P, K elements were put forward. The results are as follows: (1) concentrition of nutrient elements in organs of the oil-tea standing crops tends toward N>K>Mg>Ca>P, the highest concentration of nutrient elem...

Abstract: Reliable Web service transaction mechanism is one of the essential parts in the Service Oriented Architecture(SOA),and transaction it's self needs a mechanism for failure recovery.A pattern which combination with the feature of Web service transaction and the technique of trigger in database systems,is able to facilitate the application of Web service transaction process model.
SUPERPLASTIC BEHAVIOUR OF NiAl AND Ni3Al DUPLEX ALLOY
NiAl和Ni3Al双相合金的超塑性变形

Abstract: 研究了NiAl和Ni3Al双相合金在高温超塑性变形行为.结果表明:该合金在975至1025℃的温度范围及应变速率为152×10(-4)s(-1)时,表现出超塑性变形行为;1000℃时最大拉伸延伸率为149%,此时对应的应力敏感指数为0.375.该合金的超塑性形变可用经验公式ε=Aσ(2.67)exp(-303000/RT)来表示。对拉伸后试样的金相和TEM研究表明,合金中NiAl和Ni3Al两相在高温能够较好地协同形变,超塑性是由变形过程中发生的连续回复与再结晶过程来实现的.
一种基于颜色特征的图像检索方法
元元,
中国图象图形学报 , 2006, DOI: 10.11834/jig.2006012309
Abstract: 提出了一种新的基于颜色自组织聚类的图像检索算法。该算法根据颜色在图像中的分布信息,通过对像素点的加权处理确定最佳的颜色初始聚类数目,将经过加权处理的像素点进行聚类,得到图像主要颜色的统计特征,同时,在分析了主要颜色在图像中的散布情况后,利用主色的矩特征来描述各个主色在图像中的空间分布特征,结合颜色的统计特征与空间分布特征来描述图像的内容,保证了图像在局部和整体上的一致性,实验结果证明,该算法的检索精度明显要高于传统的仅基于颜色统计特征的检索精度。

SEISMIC ATTRIBUTE ANALYSIS AND APPLICATION IN SUBTLE TRAPS EXPLORATION
地震属性分析及其在岩性油气藏勘探中的应用

天然气地球科学 , 2006,
Abstract: Application of seismic attribute in subtle traps exploration makes most of seismic information, and seismic attribute analysis is a key of application of attribute in subtle traps exploration. The new method for seismic attribute analysis colligates information of seismic, logs and geology by crossplot and broadcast and cluster with the methodology of science instead of analysis with handcraft and eyeballing. With the method, seismic attribute analysis plays an important role in subtle traps exploration.
