| Abstract: | A DEW video watermarking algorithm based on energy difference ratio was proposed.This algorithm embeds watermarks in energy-equally-distributed areas of I-frame video image blocks.Every I-frame has the same embedded-watermarking.Experimental results show that the proposed watermarking algorithm not only has better performance in the aspect of robustness but also has stable rates and high reliability in the test. |

| Keywords: | Video watermarking Energy difference ratio DEW I-frame |
