Claim One:
1. A method for analyzing an image, comprising: receiving the image by an image processor from a data storage device; locating, via the image processor, a contour of a feature in the image; identifying, via the image processor, a curved segment of the contour that is associated with noise; rotating, via the image processor, the curved segment of the contour in a Cartesian coordinate system so as to express the curved segment in functional form; smoothing, via the image processor, the curved segment of the contour in the Cartesian coordinate system so as to reduce the noise that is associated with the curved segment, thereby providing a smoothed segment; transforming, via the image processor, the smoothed segment from the Cartesian coordinate system to a natural coordinate system, thereby providing a transformed segment; fitting, via the image processor, a line to the transformed segment; and determining, via the image processor, a radius of curvature of the curved segment based on the line fitted to the transformed segment.
