The steganographic payload is a well-known metric to evaluate the security of steganography and performance of steganalysis,while the impact of image texture diversity on steganography is usually ignored.This paper presents a new metric of image texture complexity based on the high dimensional image statistical model to measure the texture difference of images.Extensive experiments are conducted to make comparison of the detection performance under different embedding rates and image complexities.Experimental results indicate that the proposed method can be effectively used to evaluate the security of steganography.
