Transform domain watermarking: adaptive selection of the watermark's position and length
Vassilis E. Fotopoulos, Athanassios N. Skodras · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2003
Transform domain methods have dominated the watermarking field from its early stages. In these methods some coefficients are selected and modified according to certain rules. The two most important numbers in this process are the length and the position of the watermark. These are usually heuristically chosen. In order to handle this problem, an adaptive scheme for the selection of the proper coefficients is analysed in the present communication.
