Description¶

The images in RAVIR dataset were captured using infrared (815nm) Scanning Laser Ophthalmoscopy (SLO), which in addition to having higher quality and contrast, is less affected by opacities in optical media and pupil size. RAVIR images are sized at 768 × 768, captured using a Heidelberg Spectralis camera with a 30° FOV and compressed in the Portable Network Graphics (PNG) format. Each pixel in the images has a reference length of 12.5 microns. RAVIR project was carried out with the approval of the Institutional Review Board at UCLA and adhered to the tenets of the Declaration of Helsinki.

Note: If you previously downloaded the dataset ( before Aug 16, 2022), please remove case IR_Case_002.png from test set images and predictions as it is a duplicate image. Failure to do so will result in errors in getting the segmentation performance from the test set server. Nothing needs to be changed if the dataset is downloaded after this date.
