| Abstract: | This paper analyzes several kinds of existing measurement algorithms for the image scrambling degree.Then it proposes an image scrambling degree algorithm based on geometric measurement according to two considerations：distance excursion and direction excursion between the adjacent pixels of the image before scrambling and after scrambling.Finally, through comparison and analysis,it can prove that the algorithm has better properties,such as practicability,validity and advantage etc. |
