Computing a curve to approximate data points is a problem encountered frequently in many applications in computer graphics, computer vision, CAD/CAM, and image processing. In this paper, the concept of interval B-spline curve fitting is introduced. The four fixed Kharitonov's polynomials (four fixed B-spline curves) associated with the set of given interval data points and the interval B-spline curve are obtained. Then the problem is converted into determining a set of fixed control points that generates a B-spline curve for a set of given four fixed Kharitonov's polynomials (four fixed B-spline curves) associated with the interval data points.
