Watermark Detection for Video Bookmarking Using Mobile Phone Camera

Abstract : In this paper we investigate a watermarking application for bookmarking of video content using a mobile phone's camera. A content identifier and time-stamp information are embedded in individual video frames and decoded from a single frame captured from a display device, allowing to remember ('bookmark') scenes in the video. We propose a simple watermarking scheme and blind image registration to combat the inherent geometric distortion due to digital/analog conversion. The work-in-progress shows promising results over previous approaches.
