Dataset Information
Additional Information
* The dataset was acquired and annotated by professional physicians at 'Hospital Universitario de Caracas'. * The subjective judgments (target variables) were originally done in an ordinal manner (poor, fair, good, excellent) and was discretized in two classes (bad, good). * Images were randomly sampled from the original colposcopic sequences (videos). * The original images and the manual segmentations are included in the 'images' directory. * The dataset has three modalities (i.e. Hinselmann, Green, Schiller). * The target variables are expert::X (X in 0,...,5) and consensus.
