Effect of selected attribute filters on watermarks
Florence Tushabe, Michael H. F. Wilkinson · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2010
This paper shows the effect that selected attribute filters have on existing watermarks of an image. Seven transform domain watermarking algorithms and five attributes have been investigated. The attributes are volume, gray-level, power, area and vision. Apart from only one, all of the filters have been found not to affect the underlying watermarks.
