Cross-modal quassar image dataset
This dataset mainly includes five types of dataset images from WISE, SDSS, and SKYMAPPER surveys, obtained according to different screening principles. We cropped the images into 64x64 images according to the right ascension and declination coordinates of the quasars in DR16Q, and the images were saved as .mat matrix files. A description of the relevant details is included in https://github.com/Valar-hub/MMLPhoto-z.
