Abstract
Systems, methods, and software are disclosed herein that improve computer vision technology in general, and 4D scene reconstruction in particular. An artificial intelligence (AI) image processing system employs multiple dynamic neural radiance fields (NeRFs) to render two-dimensional (2D) images of a four-dimensional (4D) scene from different viewpoints and different instances of time. The AI image processing system collects viewing parameters for rendering a two-dimensional (2D) image of the 4D scene, such as from a desired viewing direction and at a desired instance of time. The system then executes the multiple dynamic NeRFs to obtain, based on the viewing parameters, color and volume density values for voxels associated with pixels in the 2D image. The system then renders the 2D image based on a combination of the color and the volume density values obtained from the multiple dynamic NeRFs.
