Geometric distortion compensation of printed images containing imperceptible watermarks

This work proposes a digital watermarking system using camera phones and high quality printed images, which contain imperceptible watermarks. The system compensates for geometric lens distortion in order to extract the imperceptible watermarks correctly from the camera-captured images.
