AI Technical Summary
In existing technologies for digital artworks, the watermark placement methods lack constraints on local perspective structures, making it difficult to naturally integrate with the spatial structure of the artwork. Furthermore, the watermark placement and cropping processes lack effective mechanisms for determining recognizability. The watermark rendering methods are simple, resulting in limited visual fusion effects, which fails to meet the overall aesthetic requirements of digital artworks.
By introducing a perspective constraint mechanism for geometric alignment during the watermark placement stage, a recognizability judgment mechanism for screening during the placement evaluation stage, and a fusion processing method during the rendering stage, the spatial fit, structural usability, and visual consistency of the watermark and the digital artwork are ensured.
It improves the naturalness, stability, and recognizability of watermarks in complex artistic scenarios, generating natural, recognizable, and visually high-quality visible watermark results, meeting the practical application needs of copyright identification for digital artworks.
