Spectro-polarimetric Dataset

We provide a spectro-polarimetric dataset. This dataset consists of full-Stokes images for both hyperspectral and trichromatic scenes. Hyperspectral dataset has 311 scenes and trichromatic dataset has 2022 scenes.

For more details, see our paper on Spectral and Polarization Vision: Spectro-polarimetric Real-world Dataset.
