Abstract: A three-dimensional (3D) scene is generated from non-aligned generic camera priors by producing a tri-plane representation for an input scene received in random latent code, obtaining a camera posterior including posterior parameters representing color and density data from the random latent code and from generic camera priors without alignment assumptions, and volumetrically rendering an image of the input scene from the color and density data to provide a scene having pixel colors and depth values from an arbitrary camera viewpoint. A depth adaptor processes depth values to generate an adapted depth map that bridges domains of rendered and estimated depth maps for the image of the input scene. The adapted depth map, color data, and scene geometry information from an external dataset are provided to a discriminator for selection of a 3D representation of the input scene.

Abstract: The information processing apparatus obtains a distribution characteristic representing an attribute of a color included in an acquired first image group and determines the number of times of learning based on the distribution characteristic. The information processing apparatus generates a data set consisting of a set of the first image group and a second image group corresponding to the first image group and by using the generated data set, generates a learning model by performing learning using a network based on the determined number of times of learning.

Abstract: The present disclosure provides neural fields for sparse novel view synthesis of outdoor scenes. Given just a single or a few input images from a novel scene, the disclosed technology can render new 360° views of complex unbounded outdoor scenes. This can be achieved by constructing an image-conditional triplanar representation to model the 3D surrounding from various perspectives. The disclosed technology can generalize across novel scenes and viewpoints for complex 360° outdoor scenes.
