Code for J. Wang, J. Li, Y. Shi, J. Lai and X. Tan, "AM3Net: Adaptive Mutual-learning-based Multimodal Data Fusion Network," in IEEE TCSVT, 2022. We conducted the experiments on the hyperspectral and lidar dataset(Houston and Trento) and multispectral and synthetic aperture radar data (grss-dfc-2007 datasets).
