Image segmentation using random walker algorithm
by Guanyu Wang, Advanced Graphics Lab


I will introduce a method for performing multilabel, interactive
image segmentation. Given a small number of pixels with pre-defined
labels, one can analytically and quickly determine the probability that
a random walker starting at each unlabeled pixel will first reach one of
the pre-labeled pixels.

By assigning each pixel to the label for which the greatest probability
is calculated, a high-quality image segmentation may be obtained.

Guanyu Wang is a first-year Masters student in Computer Science at the
University of New Mexico. His academic advisor is Joe Kniss.
