A New Digital Watermarking Scheme Applying Locally the Wavelet Transform

摘要

Generally, the wavelet transform is applied for watermarking, where a whole image is transformed to the fre- quency domain. However, many schemes which adopt the wavelet transform are weal for StirMark attack designed to affect locally such as rotation, extension, reduction etc. In this paper, we pro- pose a new scheme which applies the wavelet transform locally and has a tolerance for StirMark attack.
