Abstract
Aiming to address the issue of noticeable visual quality changes before and after embedding secret information, this paper proposes a novel 3D model information hiding algorithm based on grid saliency. Firstly, use the half-edge folding algorithm to simplify the 3D model. Second, according to the processed data set, the model was effectively labeled by the multi-scale weighted fusion method, and the local significance region was divided. Next, the significant region is divided into key points, sub key points, and background points using Mean Shift clustering analysis. Project the sub-key points onto a two-dimensional plane and embed the secret information according to the interval expression conversion strategy. The distortion rate of the model is greatly reduced. It improves the capacity of secret information embedding while ensuring invisibility performance.
