Automatic Detection of Digital Zooms (WP-L1)

Author(s) : Jerome Buzzi (DO Labs, France) Frederic Guichard (DO Labs, France)

Abstract : We propose and evaluate a method to determine whether a given digital image is the result of a digital zoom in or more generally of a linear interpolation. This information is important to some post-processing. It also sheds some light on the actual resolution of some digital cameras.
