Watermark Detection for Video Bookmarking Using Mobile Phone Camera
نویسندگان
چکیده
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.

A Fundamental Study on Digital Video Watermarking for Two-Dimensional Barcodes Displayed on Mobile Phone Screens
Two-dimensional barcodes (2D codes) have become common as an authentification way of e-tickets and e-coupons. However, easy replication by using other mobile phone camera is apprehended. This paper proposes a method for detecting copied 2D code by a semi-fragile digital video watermark which can be destroyed by replication. Compared to digital image watermarking, it is more difficult to copy 2D...
متن کاملAssessment of camera phone distortion and implications for watermarking
In this paper, the distortion introduced by cameras of smart phones such as iPhone 3G and iPhone 3GS is measured and quantified. In particular, the spatial frequency response (SFR) of a mobile camera phone is measured [1]. A new robustness metric that relates camera phone quality to watermark robustness is defined. Experiments were conducted using watermarked images to verify the predictions ma...
متن کاملToward an interactive poster using digital watermarking and a mobile phone camera
A method for embedding a watermark in print media, posters or other paper printouts and reading thewatermark information blindly with a camera phone is proposed. A subtractive-additive embeddingmethod is applied inwhich the message is coded with a directed periodic pattern. The message is detected and read by searching regularities in the autocorrelation function of a periodic signal. The robus...
متن کاملCamera Based Watermark Extraction – Problems and Examples
Cameras are more and more common in mobile phones and this creates new opportunities and threats to digital watermarking. We discuss about the difficulties that occur while reading a watermark with a digital camera or a camera phone and what kind of applications and technical solutions have already been invented. Not much research has been done on this field but commercial applications have alr...
