结合贝塞尔曲线的石头画生成式伪装、恢复方法及系统
By combining the method of generating stone paintings with Bézier curves, the semantic lack and self-similarity constraints of non-natural carriers for information hiding in existing technologies are solved. This achieves high-quality secret information concealment and secure embedding, with good visual effects and key dependency.

AI Technical Summary
Existing methods for hiding information without a natural carrier suffer from the lack of actual semantics in textured images, making it impossible to effectively conceal secret information. Furthermore, fractal embedding requires strict mathematical constraints on the self-similarity of the whole and the local, which can easily lead to embedding anomalies.
By combining Bézier curves to generate stone paintings, the outer contour boundary of the foreground region of the mask image is extracted, and triangulation and filtering are performed to generate stone paintings containing secret information. The correspondence between triangles and secret bits is controlled by the user key to generate realistic stone paintings and fill them with color, ensuring embedded security and visual quality.
The generated stone paintings have the same features as the cover images, are rich in semantic features, can effectively conceal secret information, have good visual quality, are not prone to triggering steganography anomalies, and have good key sensitivity and high-precision secret information extraction.
