optical remote sensing image

The ORSSD dataset consists of 800 optical remote sensing images with corresponding pixel-level annotations, divided into a training set of 600 images and a test set of 200 images. The EORSSD dataset is an extension of ORSSD, adding 1200 ORSIs for a total of 2000 images, and is split into 1400 training images and 600 test images. The ORSI-4199 dataset includes 2000 training images and 2199 testing images, making it the most challenging optical RSI-SOD dataset.
