摘要

To address the challenges of Remote Sensing Scene Classification (RSSC), including considerable classes, intricate spatial data, intra-class variability, and high inter-class similarity, Lightweight Heterogeneous Neural Network (LH-Net) is proposed. LH-Net facilitates feature extraction across diverse dimensions, including spatial information, by leveraging HetConv. Subsequently, the Heterogeneous Block replaces the DSC in MobileNetV1. Evaluation on the UCMerced_LandUse dataset demonstrates LH-Net’s superior performance over traditional CNN models in RSSC, achieving significantly improved accuracy with only a modest increase in FLOPs and parameters.
