New HyperImageNet benchmark advances hyperspectral land-cover classification

Researchers have introduced HyperImageNet, a new large-scale benchmark designed for detailed hyperspectral land-cover classification. This dataset includes over 26,000 airborne hyperspectral image patches, each with 224 spectral bands and categorized into 138 distinct land-cover types. HyperImageNet offers raw imagery, pixel-level semantic labels, and object-level instance masks, supporting both semantic and instance segmentation tasks. The benchmark also includes an open-environment evaluation framework and assesses the performance of the HyperFree foundation model, demonstrating its utility for advanced remote sensing research.
