COVD-CHASEDB1 for Vessel Segmentation

• Configuration resolution (height x width): 960 x 960

The dataset available in this file is composed of DRIVE, STARE, IOSTAR vessel and HRF (with annotated samples).

For details on those datasets, consult:

• See bob.ip.binseg.data.drive

• See bob.ip.binseg.data.stare
