Abstract

In this contribution a preprocessing technique for information flow control in compressed video sequences is presented. It consists of resolution adaptation in spatial and temporal domains and is based on a wavelet multiresolution representation. The technique allows to reduce information peaks during frames sequences characterized by large motion and to reduce artifacts introduced by coders operating at high compression rates. Extending previous works, the contribution exploits the decreasing perceptive resolution versus the angular distance from the visual line of sight (foveal zone) providing additional features related to motion activity.
