Graphics, Imaging, and Games Lab

I uploaded a gallery of images to demonstrate the behavior of the cumulative range geodesic filter at various parameter values.

The gallery is available here.

This version of the filter is a replication of the prototype version created by Dr. Mould (see http://gigl.scs.carleton.ca/node/481).

From the images, it is evident that the masks created by the filter can be very irregular in shape. As the "gamma" parameter increases, the mask boundaries are pulled closer to the source pixel, resulting in more circular mask shapes and a softer output image.
