Abstract
The present invention relates to embedding data in material. Material means one or more of video material, audio material and data material. Video material in this context may be still images or moving images. There is provided an apparatus comprising a transformer for transforming transform domain data into spatial domain data and a combiner for receiving material and combining said spatial domain data with said material to form data embedded material. Hence, the material is not subject any transformation at all.
Claims30
An apparatus comprising:
- a transformer for transforming transform domain data into spatial domain data;
- and
- a combiner for receiving material and combining said spatial domain data with said material to form data embedded material.
The apparatus of claim 18, comprising:
- a strength adapter for adapting the strength of said transform domain data in dependence on said material,
- wherein said transformer transforms said strength adapted transform domain data into strength adapted spatial domain data and said combiner arithmetically combines said material and said strength adapted spatial domain data.
A method comprising the steps of:
- a) transforming transform domain data into spatial domain data;
- and
- b) combining said spatial domain data with material to form data embedded material.
