Abstract :
In wireless and mobile environments, universal media access is a key concept to facilitate efficient transmission of visual data by simple bitstream adaptation which relies on scalable coding schemes. Six different blind watermarking schemes are compared with respect to their watermark detection performance on scaled visual data. Specifically, resolution and quality scalability is considered in JPEG2000 and JPEG and the found watermark detection performance is related to the employed watermarking embedding strategies. It is found that in wireless environments, careful adjustment between watermark embedding and scalability modes is required to result in the desired watermark detection properties.
