Embodiment 1
[0066] figure 1 It is the overall frame diagram realized by this embodiment.
[0067] 1) Calculate the disturbance score
[0068] The method proposed in literature [1][2] can find the edge position pixels in the image very well, and the obtained steganographic image has higher visual quality, and the disturbance distortion measurement method proposed in literature [4] can have higher anti- Detectability, based on the above three steganography methods, the present invention proposes a new disturbance measurement method, which makes the steganographic image have higher visual quality and better anti-detection performance.
[0069] The present invention first uses the disturbance distortion measurement method proposed in literature [4] to calculate the disturbance distortion score of the carrier image X, and literature [4] proposes a local texture pattern (crmiLTP) with complementation, rotation and mirror invariance to describe the binary value The texture of the image, first ...
