Abstract: An image converter identifies a subset of frames in a two-dimensional video and determines a global camera motion value for the subset of frames. The image converter also determines a dense motion value for a plurality of pixels in the subset of frames and compares the global camera motion value and the dense motion value to calculate a rough depth map for the subset of frames. The image converter further interpolates, based on the rough depth map, a depth value for each of the plurality of pixels in the subset of frames and renders a three-dimensional video from the subset of frames using the depth value for each of the plurality of pixels.
