Abstract :
The decoding of convolutional codes using the list Viterbi algorithm is proposed for data hiding applications. The performance of this technique is evaluated for wavelet-domain information hiding and is shown in many cases to be advantageous in comparison to the widely used turbo codes for efficient extraction of information embedded in digital images.
