Abstract

The trigonometric polynomial spline surface generated over the space {1, sint, cost, sin2t, cos2t} is presented in this work. The proposed surface can automatically interpolate all the given data points and satisfy C² continuous without solving equation systems. Then, image zooming making use of the proposed surface is investigated. Experimental results show that the proposed surface is effective for dealing with image zooming problems.
