ABSTRACT:
In order to enlarge or reduce a digital image, the interpolation signals between discrete original pixels used to calculate output pixel values are calculated by an FIR digital filter using as an interpolating function a function obtained by composing a function based on a cubic convolution method and a function based on a bilinear method.
