Abstract: A two-dimensional image to be converted to a first three-dimensional image may be received. A second three-dimensional image that is visually similar to the two-dimensional image that is to be converted may be identified. A feature-to-depth mapping function may be computed for the first three-dimensional image by using an approximate depth map of the second three-dimensional image that is visually similar to the two-dimensional image that is to be converted. The feature-to-depth mapping function may be applied to a plurality of pixels of the two-dimensional image to determine a depth value for the plurality of pixels of the two-dimensional image. The first three-dimensional image may be generated based on the depth values for the plurality of pixels of the two-dimensional image.

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.

Abstract: A combined depth map is generated for a monoscopic image based on a weighted combination of a color depth map, a spatial depth map, and a motion depth map for the image, each describing the depth of pixels in the image relative to the image plane. The color depth map determines the depth of pixels according to their color, the spatial depth map determines the depth of pixels according to their location in the image, and the motion depth map determines the depth of pixels according to their motion in the image. Each of the depth maps is associated with a weight that is used to generate the weighted combination. The weights are adaptive to account for variation between different monoscopic images.
