Abstract :
Capacity and reliability are two important properties of digital watermarking. In this paper, we realize an adaptive watermarking capacity analysis method, and discuss watermarking capacity in this scenario. We also analyze the relation between watermarking capacity and watermark detection bit error rate (BER), and derive the relation between capacity and the limit of BER. According to the result of our research, watermark detection BER is mainly influenced by the watermarking average energy and watermarking capacity. The BER rises with the increase of watermarking capacity.
