One of the most commonly utilized clinical tests performed today is
the routine evaluation of peripheral blood smears. In this paper, we
investigate the design, development, and implementation of a robust
color GVF active contour model for performing segmentation using a database
of 1,791 imaged cells. The algorithms developed for this research
operate in
Luv color space and introduce a color gradient and L_{2}E robust
estimation into the traditional GVF snake. The accuracy of the new
model
was compared with the segmentation results utilizing a mean-shift
approach, the traditional color GVF snake and several other commonly
utilized segmentation strategies. The unsupervised robust color snake
with L_{2}E robust estimation was shown to provide results which
were
superior to the other unsupervised approaches and was comparable with
supervised
segmentation as judged by a panel of human experts.
