摘要： 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.

摘要： An image converter compiles three-dimensional content into a data store, identifies a number of stereo image pairs from the three-dimensional content, computes a depth map for each of the stereo image pairs from the three-dimensional content, and partitions the stereo image pairs in the data store into multiple categories. The image converter determines a depth cue for each of the categories based on the depth map for each of the stereo image pairs in each category. The image converter computes a depth map for a category associated with a two-dimensional input image based on the determined depth cue and renders a three-dimensional output image from the two-dimensional input image using the depth map for the category.

摘要： A system and methodology provide for generation of a stereo video from a mono video. A mono video is partitioned into shots, where each shot including one or more frames of the mono video. The mono video frames are used as the left frames in the stereo video. Depth parameters are determined for each shot. A pixel depth map is created for each frame of each shot. The right frames for the stereo video are created by shifting pixels from the left frames laterally to occupy new locations in the right frames. A pixel's shift is based on the depth parameters and the pixel depth. In aggregate, pixel shifts will cause objects to appear in different locations in the right frame relative to where they appeared in the left frame. The effect upon the viewer is that the stereo video will provide an enhanced illusion of depth for the viewer.
