NeX: Real-Time View Synthesis With Neural Basis Expansion

Neural basis functions Reflectance coefficients Figure 1: (a) Each pixel in NeX multiplane image consists of an alpha transparency value, base color k 0 , and view-dependent reflectance coefficients k 1 ...k n . A linear combination of these coefficients and basis functions learned from a neural network produces the final color value. (b, c) show our synthesized images that can be rendered in real time with view-dependent effects such as the reflection on the silver spoon.
