Application of U-net models in estimating forest canopy closure based on multi-source remote sensing imagery

Forest Canopy Closure (CC) is vital for assessing forest ecosystems. This study integrates multispectral imagery with enhanced U-Net models (U-Net, U-Net++, U-Net3+) to achieve cost-effective large-scale CC estimation. These models are optimized by reordering the network output layers and enhancing...
