hyperspectral data

PU and PC datasets both were obtained through the reflective optics spectrographic Image system (ROSIS) sensors in Pavia, which is located in the northern region of Italy. The PU image has 610 × 315 pixels, 144 bands in the range of 430 - 860 nm, and 1.3-m spatial resolution. The PC image has 1906 × 715 pixels, 102 bands in the range of 430 - 860 nm, and 1.3-m spatial resolution. Both datasets include 9 distinct categories. Houston data was acquired over the University of Houston campus and its neighboring area on June 23, 2012. The Houston image has 349×1905 pixels, 144 bands in the range of 380-1050 nm, and 2.5-m spatial resolution. There are 15 land cover types in the image. DC dataset is an airborne hyperspectral image collected over the Washington DC Mall, acquired by the Hyperspectral Digital Imagery Collection Experiment (HYDICE) sensors. It was provided with the permission of the Spectral Information Technology Application Center of Virginia, which was responsible for its collection. The DC image has 1208 × 307 pixels, 191 bands in the range of 400 - 2400 nm, and 2.8-m spatial resolution, including 7 categories. OHID-1 dataset was acquired by spaceborne Complementary Metal-Oxide-Semiconductor (CMOS) sensors. OHID-1 dataset comprises 10 hyperspectral images sourced from diverse regions of Zhuhai City, China. We choose one of the images as our experimental object, named OHID-1-4. The OHID-1-4 image has 512 × 512 pixels, 32 bands in the range of 400 - 1000 nm, and 10-m spatial resolution, which includes 5 categories.
