Abstract
Systems, methods, software, and devices are disclosed herein for training a neural network using multiple images of a scene captured from different viewing directions. The training is expedited by first determining foreground pixels in each of the multiple images, and then selecting a non-uniform sample of pixels from each of the multiple images such that the foreground pixels are overrepresented in the non-uniform sample of pixels relative to background pixels. The neural network may then be trained using radiance values of voxels on rays propagating from each of the non-uniform sample of pixels along a corresponding viewing direction into the scene.
