Abstract:
Quantization index modulation is one of the best methods of blind watermarking, due to
its simplicity, low complexity, and good rate-distortion-robustness trade-offs. This thesis
deals with a study of audio watermarking algorithms based on quantization. The main
results include the development of ve novel audio watermarking algorithms providing
performance enhancements over existing algorithms. This is accompanied by extensive
experimentation to validate the performance bene ts of the proposed algorithms, in
presence of standard watermarking attacks.
