Abstract
To decode information that is steganographically encoded (“watermarked”) within an image, the image is first transformed into another domain. A variety of techniques can then be applied in furtherance of the decoding operation.
Claims10
A method of decoding information steganographically encoded within an image, the method including:
- receiving a set of input data that represents the image in the pixel domain;
- and
- performing a domain transformation on the input data to produce transformed data that represents the image in a different domain.
