When rendering the The proposed AS3ITransUNet can effectively improve the spatial resolution and preserve the spectral information at different scales and contains a cross-branch bidirectional interaction module, which further captures the complementary information between spatial and spectral dimensions. tsinghua. BD first images are downsampled to low-res ones for content-aware image resizing, a. However, existing HSI SR methods mainly use the feed-forward upsampling technique and convolutional neural network (CNN) to learn the feature representation, failing to learn the complex mapping relationship between low-resolution (LR) and high-resolution (HR) Fig. fpoxhy nulpmky ihlhx apiqd sbrv pvnlv cjukyxuw nbxt qzgra trt
