SCALE-TORT Database
SCALE-TORT database contains a total of 226 FP/IR paired arterial vessel curves and 245 FP/IR paired vein vessel curves, all 471 paried curves where semiautomatically extracted from the original images.
- Folder 'im_arteries' with: 1.1 226 croped images from FP of retinal arteries 1.2 226 croped images from IR of retinal arteries
- Folder 'im_veins' with: 2.1. 245 croped images from FP of retinal veins 2.2. 245 croped images from IR of retinal veins
- 1 A folder 'arteries_data_coords' containing text files, one per image in the 'im_arteries' folder, with the coordinates of the corresponding curve.
- 1 A folder 'veins_data_coords' containing text files, one per image in the 'im_veins' folder, with the coordinates of the corresponding curve.
- Matlab structure for arteries annotations over the images
- Matlab structure for veins annotations over the images

The study employed high quality non-mydriatic (i.e. pupil dilation is not required) fundus photography (FP) (Oculus Nidek AFC-230, 45 FOV) and a infra-red reflectance (IR) en face image obtained by scanning laser ophthalmoscope (SLO) (Heidelberg Spectralis, 30 FOV) to produce representative images of the retina and optic nerve. In order to prove the scale invariance property of tortuosity metrics, ophthalmological photographs from 18 subjects, both eyes, were randomly extracted from the ...
