Title: Innovations of Alexander Olegovich Zhirkov
Introduction
Alexander Olegovich Zhirkov is a prominent inventor based in Moscow, Russia. He has made significant contributions to the field of 3D modeling and representation through his innovative patents. With a total of 7 patents, Zhirkov's work has advanced the way 3-dimensional objects are represented and manipulated in digital environments.
Latest Patents
Zhirkov's latest patents include an apparatus and method for depth image-based representation of 3-dimensional objects. This invention provides a family of node structures that represent 3D objects using depth images, which can be integrated into the MPEG-4 AFX framework for polygonal 3D representations. The main formats of this family include DepthImage, PointTexture, and OctreeImage. DepthImage represents an object through a union of its reference images and corresponding depth maps. PointTexture represents the object as a set of colored points parameterized by projection onto a 2D grid. OctreeImage converts the same data into a hierarchical octree-structured voxel model, along with a set of compact reference images and a tree of voxel-image correspondence indices. Both DepthImage and OctreeImage have animated versions, where reference images are replaced by videostreams. These DIBR formats are particularly useful for constructing 3D models from 3D range-scanning and multiple source video data. The MPEG-4 framework allows for a variety of representations from the DIBR formats, providing flexible tools for effective 3D model work. Compression of the DIBR formats is achieved by applying image and video compression techniques to depth maps and reference images.
