Based on a new viewpoint that digital image is considered as mass with non-uniform densities, a novel scrambling degree rule is presented that can be used to measure the scrambling degree by the distance between the center of mass and the center of figure. Compared with other rules, this rule has the distinguished advantage that it can measure the scrambling degree of any scrambled image using only the information of image. Experimental results show that its performance is superior to other rules.
