Smart zooming refers to certain digital image processing algorithms that enable the examination of detail ordinarily obscured by pixelation effects. These algorithms use radial basis function interpolation to smooth image blockiness due, for example, to magnification by pixel replication. They may permit more smoothing flexibility while retaining more image detail than conventional convolution smoothing methods.
