Multisource Remote Sensing Data Classification Based on Convolutional Neural Network

基于CNN的多源遥感数据分类

本文提出了two-branch CNN用于多源遥感数据,该结构通过提取HSI和other sources(LiDAR or VIS)特征,然后全连接层融合。

对于HIS branch:是一个dual-tunnel CNN,包含spectral(光谱)tunnel 和 spatial(空间)tunnel。光谱 tunnel 采用 1D conv ,空间 tunnel 采用 2D conv。再将两者输出特征放到全连接层,softmax分类器。
