Abstract
Watermarking capacity determines how much information can be carried in an image. Shannon formula is usually used to calculate it. While in this paper, it is considered that the watermarking capacity relies directly on the fidelity measure function. After the watermarking embedding process model is discussed, watermarking capacity formula and maximum watermarking capacity formula are proposed. Then, the watermarking capacity using PSNR as fidelity measure function is discussed. The conclusion that PSNR is not suitable to evaluate watermarked image is obtained.
