DATA HIDING IN H.264 VIDEO FOR LOSSLESS RECONSTRUCTION OF REGIONOF INTEREST

摘要

In this paper, we propose a method to protect faces in videosurveillancernscenes. Our method deletes any visible informationrnof faces in a video and uses a data-hiding techniquernto embed information in the video that allows further reconstructionrnof the faces if needed. When the entire informationrnneeded for reconstruction is embedded, we obtain infiniternPSNR for the face regions.
