Agricultural village is an important rural type in China. The evolution process and mechanism of its cultural landscape are different from those of the industrialized village. The paper focuses this t
Taking Nanjing as a case, the paper explains the spatial behavior differences existing in the information technology use among different groups of residents and households, by virtue of analyzing the
A non-dimensional relative sensitivity coefficient was employed to predict the responses of reference crop evapotranspiration (ET0) to perturbation of four climate variables in Taoer River Basin of th
由于交叉皮层模型(intersecting cortical model,ICM)图标信号具有平移、旋转以及尺度不变性,因此,基于ICM的图像匹配算法能够提高实时目标图与基准目标图的匹配率,但根据ICM图标信号获取的不变特征对噪声信号较敏感。针对这一问题,提出了基于ICM和小波变换的图像匹配识别算法。仿真结果表明,本文算法在平移、尺度、旋转变化以及噪声环境下仍具有较高的匹配率。
提出了一种新的基于柯西分布的光照模型(shading model,SM)变化检测方法。在一种快速动态背景图像初始化的基础上,建立了Gaussian统计背景模型;基于使用统计假设检验方法检测变化区域的结果,利用YCbCr颜色空间的亮度、颜色信息,识别和消除视频序列图像中的阴影和反光等。试验表明,该文所提出的方法可以承受整体或局部的、缓慢或突然的背景光线变化,以及由场景背景中小的背景扰动、阴影或反光导
提出了一种利用支持度矩阵生成频繁项集的Apriori改进算法。通过上三角分块稀疏矩阵的行列性质和非频繁列之间的约束关系,改进的算法避免了Apriori连接步中大量非频繁候选k-项集的产生及其在剪枝步中(k-1)-子集的分解和判断。该算法能够有效地压缩搜索空间,降低Apriori连接和剪枝步骤的开销。
对矢量目标如建筑物、注记等形状的识别通常是基于栅格数据的,研究的基点是像素,其不足之处是准确率不高,运算量过大。对此,提出了一种新的研究思路,用矢量取代栅格(像素)作为研究的基点,识别算法以矢量为基础进行设计,采用的查询算子是傅立叶描述子。实验结果表明,该傅立叶描述子计算的查询算子区分度高,查询效果好,是一种稳健高效的识别工具。
On the basis of artificial neural network (ANN) model, this paper presents an algorithm for inversing snow depth with use of AMSR-E (Advanced Microwave Scanning Radiometer-Earth Observing System (EOS)
通过形态重构开闭算子构造了一个多尺度的目标提取和分割算法。首先用结构元素nB对影像分别作基于重构的Top-Hat和Bottom-Hat变换,得到所有不能放入nB的亮和暗的目标;然后再用结构元素(n-1)B对影像作开运算,消除所有不能放入该结构元素的目标。那么结果影像中就只剩下能同时放入nB和(n-1)B的目标。对不同尺度的结果影像进行处理,就可以得到不同尺度下的目标分割结果。重构是一个连通区域算子
