A method for image enlargement, making use of the hyperbolic Coons interpolation surface with shape parameters, is investigated in this paper. As a non-polynomial model, the hyperbolic Coons interpolation surface can represent the image better than the general interpolation methods. By altering the values of the shape parameters, the effects of image enlargement can be adjusted until achieving the satisfactory results. Experimental results show that the effects of image enlargement making use of the hyperbolic Coons interpolation surface are better than the general interpolation methods.
