METHOD FOR RENDERING RELIGHTED 3D PORTRAIT OF PERSON AND COMPUTING DEVICE FOR THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240096011 titled 'METHOD FOR RENDERING RELIGHTED 3D PORTRAIT OF PERSON AND COMPUTING DEVICE FOR THE SAME

Simplified Explanation

The disclosure provides a method for generating relightable 3D portraits using a deep neural network and a computing device implementing the method. The method allows for obtaining realistically relighted 3D portraits in real-time on computing devices with limited processing resources, achieving high-quality results without the need for complex and costly equipment.

  • Method for rendering a relighted 3D portrait:
 * Receiving input defining camera viewpoint and lighting conditions
 * Rasterizing latent descriptors of a 3D point cloud at different resolutions based on the camera viewpoint
 * Processing rasterized images with a deep neural network to predict albedo, normals, environmental shadow maps, and segmentation mask
 * Fusing predicted albedo, normals, environmental shadow maps, and segmentation mask into the relighted 3D portrait based on lighting conditions

Original Abstract Submitted

the disclosure provides a method for generating relightable 3d portrait using a deep neural network and a computing device implementing the method. a possibility of obtaining, in real time and on computing devices having limited processing resources, realistically relighted 3d portraits having quality higher or at least comparable to quality achieved by prior art solutions, but without utilizing complex and costly equipment is provided. a method for rendering a relighted 3d portrait of a person, the method including: receiving an input defining a camera viewpoint and lighting conditions, rasterizing latent descriptors of a 3d point cloud at different resolutions based on the camera viewpoint to obtain rasterized images, wherein the 3d point cloud is generated based on a sequence of images captured by a camera with a blinking flash while moving the camera at least partly around an upper body, the sequence of images comprising a set of flash images and a set of no-flash images, processing the rasterized images with a deep neural network to predict albedo, normals, environmental shadow maps, and segmentation mask for the received camera viewpoint, and fusing the predicted albedo, normals, environmental shadow maps, and segmentation mask into the relighted 3d portrait based on the lighting conditions.
