Data Set 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.

Attribute Information:

Three modalities: hinselmann, green, schiller.
