Abstract

A class of projection transform has been proposed to predict images scaled up/down in a video sequence. This camera operation corresponds to zoom in/out which are widely used for image representation. Prediction efficiency in zoom compensation has been investigated. However, analysis equations were limited for half-band case. A correction for these equations is shown in this paper.
