Efficient Image Resizing Using Finite Differences

Abstract

We present an optimal spline-based algorithm for the enlargement or reduction of digital images with arbitrary scaling factors '.This projection-based approach is realizable thanks to a new finite difference method that allows the computation of inner products with analysis functions that are B-splines of any degree n. For a given choice of basis functions… (More)
