Research output: Contribution to journalArticlepeer-review


In this paper we introduce two digital zoom methods based on sampling theory and we study their mathematical foundation. The first one (usually known by the names of ‘sinc interpolation’, ‘zero-padding’ and ‘Fourier zoom’) is commonly used by the image processing community.
