Sclera Segmentation – Annotations

We provide the annotations of 1,300 sclera images manually labeled, being 1,000 from the MICHE-I database and 300 from the UBIRIS.v2 database.

The annotations were generated by labeling only the sclera region in each image (see our paper for more details). Some samples of these annotations can be seen below:

How to obtain the Annotations

The annotations are released for academic research only and are free to researchers from educational or research institutes for non-commercial purposes.
