Title: Innovations by Pierre Alliez in 3D Watermarking Technology
Introduction
Pierre Alliez is a notable inventor based in Le Chesnay, France. He has made significant contributions to the field of 3D watermarking technology, holding a total of 3 patents. His work focuses on methods that enhance the security and integrity of three-dimensional objects.
Latest Patents
Alliez's latest patents include a method for watermarking a three-dimensional object. This method involves representing the object by a mesh, which consists of multiple vertices. The process includes computing an original thickness signature for the mesh based on various thickness values. Additionally, it determines a target thickness signature that is influenced by a watermark payload and the original thickness signature. The method modifies the position of at least one vertex to ensure that the modified mesh meets the target thickness signature while satisfying a distortion constraint. Furthermore, he has developed a method for detecting a watermark in a three-dimensional object, along with a three-dimensional object that carries a watermark and devices for implementing these methods.
Another significant patent by Alliez is a method for obtaining a payload from a three-dimensional object. This method computes a shape descriptor of a local neighborhood of a current vertex among the vertices of the object. It then obtains a target shape descriptor using a quantization grid associated with a watermark payload. The method modifies the local neighborhood by adjusting the position of at least one vertex to align the shape descriptor of the modified neighborhood with the target shape descriptor, ensuring that the current vertex remains unchanged.
