ETIS-Larib Polyp DB

ETIS-Larib Polyp DB is a database of frames extracted from colonoscopy videos. These frames contain several examples of polyps. In addition to the frames, we provide the ground truth for the polyps. This ground truth consists of a mask corresponding to the region covered by the polyp in the image, as observed in Fig. 1.

Figure 1: Example of original data and associated manual annotation from ETIS-Larib Polyp DB.

The database consists of two different types of images:

  • Original images: original/frame_number.png
  • Polyp mask : ground_truth/frame_number.bmp

At this time, only the original images will be soon available (24th of July) for the testing part of the Polyp Detection Challenge, joint event of the MICCAI 2015 conference.


Images from folder ‘Original’ are property of Lariboisière Hospital-APHP, France and ETIS laboratory, ENSEA, University of Cergy-Pontoise, France.

Images from folder ‘Ground Truth’ are property of ETIS laboratory, ENSEA, University of Cergy-Pontoise, France.
