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.
