Screen-Shooting Resilient Watermarking Scheme via Learned Invariant Keypoints and QT

Li Li, Rui Bai, Shanqing Zhang, Chin-Chen Chang, Mengtao Shi
2021 Sensors  
This paper proposes a screen-shooting resilient watermarking scheme via learned invariant keypoints and QT; that is, if the watermarked image is displayed on the screen and captured by a camera, the watermark  ...  In a partial shooting scenario, the watermark is repeatedly embedded into different regions in an image to enhance robustness.  ...  Group invariant feature transform TERA Transparency, efficiency, robustness and adaptability RST Rotation, scaling, and translation JPEG Joint photographic experts group CP CANDECOMP/PARAFAC  ...

PO uses each fragment's screen position to calculate and apply the fragment's contribution to output image pixel values.  ...  (E) PO updates the output image with contributions from the fragments, accounting for surface visibility. In this example, p1 is nearer to the camera than p0. As a result p0 is occluded by p1.  ...  Fulfilling the promise of programmable graphics-the new era of cooperatively using the CPU, GPU, and complex, dynamic data structures to efficiently synthesize imagesrequires new programming models, tools  ...
