| Abstract: | In the watermarking embedding process,there are three considerations: the amount of embedded information,invisibility and robustness.This paper calculated the watermark capacity of digital image based on several human visual system(HVS) models and several types watermarking channel,and made some comparisons,study on the role of HVS in watermark capacity. |
