Patent ID: 7194394

Claim:
A computer-implemented method of removing inaccuracies in curve fits of data representing a physical characteristic of a subject, comprising: identifying a hump or dip in a curve fit of the data; determining a relative error E 2 based on a size of the hump or dip, including calculating a difference D 2 equal to an absolute value of a difference between Y(a) and Y(b), where Y(a) is the value along the y axis of an edge point of the hump or dip and Y(b) is the value along the y axis of a local maxima or minima for the hump or dip, and calculating E 2 equal to D 2 divided by Y(a); determining if the relative error E 2 is equal to or greater than a threshold; modifying the curve fit of the data in response to determining that the relative error is equal to or greater than the threshold; and estimating the physical characteristic of the subject using the modified curve fit of the data.
