Title: Innovations of Alexandre Zaghetto
Introduction
Alexandre Zaghetto is a prominent inventor based in San Jose, California. He holds a total of 18 patents, showcasing his significant contributions to the field of technology and innovation. His work primarily focuses on advancements in mesh geometry coding and depth image generation.
Latest Patents
Zaghetto's latest patents include innovative techniques for improving depth image generation through more efficient encoding using video codecs. One of his notable inventions involves mapping depth to the luma channel without utilizing all available bits. This process generates a depth scaling factor that is incorporated into the bilinear interpolation algorithm used during rasterization. Additionally, he describes a normal filtering procedure that adjusts vertex positions based on the estimated normal from surface pixels. This method enhances the accuracy of depth image decoding by collecting pixels related to the surface of a triangle to estimate a plane and its normal. If discrepancies arise, vertex positions are iteratively adjusted to align with the estimated normal.
Another significant patent is related to mesh patch syntax, where new syntax elements extend patch types and are integrated into the V3C standard. This new syntax defines various methods for encoding meshes, including projecting connected triangles onto a 2D surface and tracking patches over time. It also allows for multiple encoding methods for vertex positions, such as explicit addition to the atlas stream or encoding using an external mesh encoder.
