Color image or video processing
First Claim
Patent Images
1. A method comprising:
- obtaining a measure or value associated with one or more color characteristics of data representing video or imagery;
based at least in part on the measure or value, determining for the data those samples that should receive steganographic encoding;
transforming at least some of the data into a transform domain; and
utilizing a programmed electronic processor, altering transform domain coefficients of the at least some data that has been transformed to steganographically encode the data.

Abstract
The presently claimed invention relates generally to color signal processing. One claim recites a method including: obtaining a measure or value associated with one or more color characteristics of data representing video or imagery; based at least in part on the measure or value, determining for the data those samples that should receiving steganographic encoding; transforming at least some of the data into a transform domain; and utilizing a programmed electronic processor, altering transform domain coefficients of the at least some data that has been transformed to steganographically encode the data. Of course, other claims and combinations are provided.
