3dcnn深度学习卫星图像土地的相关内容

基于3DCNN的深度学习卫星图像土地覆盖分类（下）

CNN进行土地覆盖分类让我们通过对数据应用主成分分析（PCA）来创建Sundarbans卫星图像的三维补丁。以下代码用于创建实现PCA的功能，创建3D补丁以及将数据按70:30的比例拆分为训练数据和测试数据。分割数据后，使用tensorflow.keras包中的to_categorical（）方法对...

遥感概论遥感是探测和监测一个地区的物理特征的过程，方法是测量该地区在一定距离(通常是从卫星或飞机)反射和发射的辐射。特殊摄像机收集远程遥感图像，这有助于研究人员“感知”地球上的事物。由带电粒子振动产生的电磁能量，以波的形式在大气和真空空间中传播。这些波有不同的波长和频率，波长越短，频率就越高。有些电...
