The growing awareness of the importance of spatial information has led to a continuously increasing demand for geospatial data.
Thus, a lot of different companies and institutions have evolved that a...
利用Unit-Linking PCNN模型，结合最小交叉熵准则，边缘检测预处理，均匀分块处理，将灰度图像分割成二值图像，在二值分割图基础上实施Unit-Linking PCNN边缘检测.边缘检测预处理以块状增强方式增强了图像对比度，强化了图像边缘；均匀分块处理实现了灰度图像的近似多阈值分割.分析了边缘检测预处理中各步骤的作用，比较了不同均匀分块数目对边缘检测结果的影响.与Canny算子和相关文献结...

在RGB空间中，将最大香农熵准则和最小交叉熵准则两种评价准则与大概率合并和小概率合并两种合并策略相结合，提出基于Unit-Linking PCNN的四种彩色图像分割方案，并在各分量分割结果基础上利用Unit-Linking PCNN实施边缘检测，合并得到彩色图像的边缘检测结果。分析了各评价准则和合并策略的优劣，比较了各分割方案条件下的图像分割和边缘检测效果。与HSV空间中得到的相关结果进行分析比较...
提出了一种基于Unit-LinkingPCNN和HSI空间的彩色图像分割新方法.在RGB空间中,由于R,G,B分量之间有很高的相关性,直接利用这些分量不能得到所需的效果.在提出的算法中,彩色图像首先被转化到HSI颜色空间,图像分解成彩色通道(H和S分量)和亮度通道(I分量).对彩色通道采用基于Unit-Link-ingPCNN的分割算法进行分割,对亮度通道采用最大类间方差阈值算法进行分割,然后将分...
