Background replacement using neural radiance field

This invention describes a way to replace the background behind a person in an image. It works by taking an image of a person and its camera's viewpoint, then using a neural radiance field (NeRF) AI model to generate a new background scene from that exact perspective. The person from the original image is then combined with this AI-generated background to create a new output image. The claims narrow this to images accessed by a messaging application on a user device.

Why it matters: Filed when NeRFs were computationally intensive. Since 2022, NeRF technology has advanced significantly, offering faster rendering and improved quality, making real-time background replacement more feasible on client devices.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedNeural radiance field machine learning system
