Abstract: Example embodiments may allow for the efficient determination of disparity information for a stereo image pair by embedding pixels of the image pair in a multidimensional dimensional vertex space. Regularly-spaced vertices in the vertex space are associated with pixels of the stereo image pair and disparity loss functions are determined for each of the vertices based on disparity loss functions of the associated pixels. The determined vertex-disparity loss functions can be used to determine vertex disparity values for each of the vertices. Disparity values for pixels of the stereo image pair can be determined based on determined vertex disparity values for respective one or more vertices associated with each of the pixels.

Abstract: Techniques for generating robust depth maps from stereo images are described. A robust depth map is generated from a set of stereo images captured with and without flash illumination. The depth map is more robust than depth maps generated using conventional techniques because a pixel-matching algorithm is implemented that weights pixels in a matching window according to the ratio of light intensity captured using different flash illumination levels. The ratio map provides a rough estimate of depth relative to neighboring pixels that enables the flash/no-flash pixel-matching algorithm to devalue pixels that appear to be located at different depths than the central pixel in the matching window. In addition, the ratio map may be used to filter the generated depth map to generate a smooth estimate for the depth of objects within the stereo image.

Abstract: Systems and methods are provided to create better-looking animated eyes for CG characters. The systems and methods set the rigging of each eye to, rather than precisely converge on a target location, converge but be rotationally or angularly offset by a certain amount to simulate correct physical eye positioning and movements. In addition, the systems and methods provide even more realistic eye appearance by taking account of the refractive properties of the cornea, e.g., which can make the pupil appear larger than it actually is. The systems and methods may further take account of a shadowing effect of the upper eye caused by the brow, eyelashes, and upper lid (as well as an effect caused by reflection from the underside of the eyelashes). This darkening of the upper portion of the eye addresses vertical eyeline discrepancies caused by the visual and optical illusion of incorrect lighting.
