Abstract
We describe effective channel coding strategies which can be used
in conjunction with linear programming optimization techniques for the
embedding of robust perceptually adaptive DCT domain watermarks. The
main contributions lie in the proposal of a coding strategy based on the
magnitude of a DCT coefficient, the use of turbo codes for effective
error correction, and finally the incorporation of JPEG quantization
tables at embedding
