[PDF][PDF] Camera based watermark extraction-problems and examples
Proceedings of the finnish signal processing symposium, 2007•Citeseer
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 already showed the potential demand for print-cam
robust watermarking methods.

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 already showed the potential demand for print-cam robust watermarking methods.
