Abstract: Shape analysis is important in classification where deviation of a contour from a model are measured. In pathology, deviation of nuclear contour from an ellipse is sometime useful in cell classification. We present a method based on Fourier series expansion, to determine the best fit ellipse to a given contour by minimizing the difference in the ellipticity factors and keeping the same area for the contour and the matched ellipse. We also compared our method to the Grid-Search method in terms of speed and accuracy. Finally we applied our method to the diagnosis of cancer cells.
