Blind Image Watermarking Based on Adaptive Data Spreading in n-Level DWT Subbands
This paper proposes a new adaptive watermarking scheme for digital images, which has the properties of blind extraction, invisibility, and robustness against attacks. The typical scheme for invisibility and robustness consisted of two main techniques: finding local positions to be watermarked and mi...
