Supervised Multispectral Image Segmentation

Welcome to our dataset for supervised multispectral image segmentation. It comes with ground-truth segmentation, seed point placements and experimental results. This dataset was created for the publication Opens external link in new window"Supervised Multispectral Image Segmentation With Power Watersheds" by J. Jordan, E. Angelopoulou. ICIP 2012.

Please cite the following paper when using the data:

2012, pp. 1585-1589.

Notes on the data:

  • The images used in our experiments are from the CAVE Multispectral Image Database.
  • As the first four pixel columns of each image do not reflect the scene, but instead appear to consist of random noise, we crop them out with the following command before creating ground-truth segmentations:
    for i in */*_ms.png; do mogrify $i -crop 508x512+4+0 +repage; done;
  • The colors of ground-truth images do not matter.
  • In the seed point images, black pixels are foreground seeds, white pixels are background seeds. The different shades of gray are not visible to the algorithms.

Algorithms used to generate segmentations:

Similarity Measure   Algorithm
L  power watersheds, q=2
SA  power watersheds, q=2
SID  maximum spanning forest
SIDSAM1  maximum spanning forest
NED  power watersheds, q=2, geod.
SOM  power watersheds, q=2, geod.
