粗糙性 meaning in English
roughness
Examples
- Roughness of choquet fuzzy integral and information fusion
模糊积分的粗糙性及信息融合 - The roughness measure of rough - fuzzy sets
粗糙模糊集的粗糙性度量 - The roughness of this model is less than or equals that of the tolerance relation - based model , and is more than or equals roughness of the non - symmetrical similarity relation - based model
该模型的粗糙性介于相容关系与非对称相似关系的粗糙集扩展模型的粗糙性之间。 - 2 . methods in frequency domain : through a comparative study , wedge and ring feature of fourier transform performs better than other features based on texture spectrum . it represents the directivity , coarseness and regularity of an image
在基于频率域的纹理分析方法中，分析了基于傅立叶变换的纹理分析方法，经两组对比实验，楔环特征能够很好的反映图象纹理的方向性、粗糙性和规律性，在检索中明显优于基于频谱的简单统计特征。 - In some projects charged by our lab such as national 863 project - " crop planting management components based on weather analyse " , anhui provincial 95 key project - " agricultural meteorology disaster evaluation system base on gis in anhui province " and the project " small coal mine security management and decision system based on gis in anhui province " , this paper combines the theory and arithmetic of rough set with gis and data mining in idss , investiges the application of rough set theory to precision analysis of attribute data and logical operation in gis , analyzes the logical operation based on rough set ( logical union , logical intersection , logical complement , mixed logical operation etc . ) , so that it can give a method y to research the gis attribute data and the uncertainty of attribute data after superposition operator , so as to express the roughness and illegibility of attribute data more accurately
在完成试验室所承担的国家863项目“基于气象分析的农作物种植管理软构件” 、省95攻关项目“基于gis的安徽省重大农业气象灾害测评系统”和“基于gis的安徽省小煤矿安全管理决策系统”等项目中，将粗糙集理论和算法与gis 、智能决策系统中的知识发现等相结合，对粗糙集理论在gis属性数据和逻辑运算精度分析中的应用情况进行了研究，分析了基于粗集的gis逻辑运算(逻辑并、逻辑交、逻辑补、混合逻辑等) ，从而为研究gis属性数据及其叠加运算后属性数据的不确定性提供了一种方法，能比较准确地表达属性数据的模糊性和粗糙性。
