Keyframes Segmentation Database
===============================

This database contains a subjective ground-truth segmentation of 120 keyframes extracted from News 2006 TRECVID video content.
The Database is organized as follows: the root folder contains 120 folders, each corresponding to one keyframe extracted from 
the content. Each folder contains:

- Three images (JPG format): associated to the keyframe (curr.jpg), a previous frame (prev.jpg), and a next frame (next.jpg).
  Previous and next frame are included to estimate motion in case it is used in the segmentation. In any case, the ground truth 
  is computed over the keyframe.
  
- The ground-truth segmentation: in the file "gt.seg". This binary file defines each pixel in the keyframe as an integer with 
  values ranging from 1 to NUMBER OF CLASSES.
  
- A list containing labels of Region-of-interest: ROI.txt is an ASCII file with a list of length=NUMBER OF CLASSES in which regions that
  are considered "of-interest" are set to 1 while the rest remain to 0. This file is useful to generate masks associated to 
  regions-of-interest such specific evaluation is performed.
