A system according to the invention identifies image data points defining a curve. The method comprises the steps of determining a start point and an end point for the curve, establishing a search space that includes at least the start point, the end point, and other image data elements comprising the curve, and searching the search space using a dynamic programming algorithm to locate image data elements corresponding to the curve. Another embodiment consistent with the present invention identifies image data points defining a curve. The method comprises the steps of determining a start point and an end point for the curve, generating a model of the curve, establishing a search space that includes at least the start point, the end point, and other image data elements comprising the curve, and searching the search space using a dynamic programming algorithm and the model for the curve to locate image data elements corresponding to the curve. Yet another embodiment consistent with the present invention matches a first curve to a second curve. The method comprises the steps of identifying a first curve, identifying a second curve, generating a higher order distance measure for comparing the first curve and the second curve, and matching the first curve to the second curve using the higher order distance measure.
