New pending patent applications are published by the USPTO on Thursdays. Today's Spotlight Applications concern aspects of digital watermarking. Assigned to KAIST (KR), the first application discloses techniques for three-dimensional mesh model watermarking method using segmentation. Assigned to Digimarc, the second application discloses techniques for rendering image content that include a digital watermark pattern at an essentially fixed scale, regardless of the size of screen on which the content is displayed.

Disclosed is a 3D mesh model watermarking method using a divisional scheme. The method of inserting a watermark into a three-dimensional (3D) mesh model includes: calculating a geometric primitive of the 3D mesh model; dividing the 3D mesh model into a plurality of mesh segments by using the geometric primitive; converting the mesh segments into mesh segments of a vertex distance-based coordinate system; inserting a predetermined watermark into each of the mesh segments of the vertex distance-based coordinate system; and restoring the mesh segments into which the watermark is inserted to a Cartesian coordinate system.
