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. 2010-01-01T00:00:00Z
