Abstract: Embodiments provide techniques for adjusting coloration of an image. A first selection of first one or more reference points within a first image is received. A second selection of a second one or more reference points within a second image is also received. Embodiments determine a coloration difference between a coloration of the first one or more reference points within the first image and a coloration of the second one or more reference points within the second image. The coloration of at least a portion of the first image is then adjusted, based on the determined coloration difference.

Abstract: Embodiments provide techniques for adjusting coloration of an image. A visual scene is captured using one or more camera devices, where the visual scene includes a reference object. Embodiments retrieve coloration information corresponding to the reference object. The coloration information generally describes coloration of the reference object under predefined conditions, such as neutral lighting conditions, desired lighting conditions, and so on. Additionally, a coloration difference is calculated between a depiction of the reference object within the captured visual scene and the retrieved coloration information. The coloration of the visual scene is adjusted based on the determined coloration difference.

Abstract: A method is provided for an optimized stereoscopic camera with low processing overhead, especially suitable for real-time applications. By constructing a viewer-centric and scene-centric model, the mapping of scene depth to perceived depth may be defined as an optimization problem, for which a solution is analytically derived based on constraints to stereoscopic camera parameters including interaxial separation and convergence distance. The camera parameters may thus be constrained prior to rendering to maintain a desired perceived depth volume around a stereoscopic display, for example to ensure user comfort or provide artistic effects. To compensate for sudden scene depth changes due to unpredictable camera or object movements, as may occur with real-time applications such as video games, the constraints may also be temporally interpolated to maintain a linearly corrected and approximately constant perceived depth range over time.

Abstract: A camera control system is provided that uses global planning to compute large, occlusion free camera paths through complex environments, incorporating visibility of a focus point into the search strategy, so that a path is chosen along which the focus target is in view or, in general, to compute a visibility graph. A visibility roadmap data structure permits precomputation of coarse representations of collision-free paths through an environment, together with estimates of pair-wise visibility between scene portions. At runtime, path planning can be done using the precomputed roadmap values to find a coarse path, and then refined to the camera path using occlusion maps computed on-the-fly. Iterative smoothing, together with a physically-based camera model, can be used to have the path followed by the camera smooth in both space and time. The data structure can be adapted at runtime to deal with dynamic occluders that move in an environment.

Abstract: In an animation processing system, generating images to be viewable on a display using a computer that are generated based on scene geometry obtained from computer readable storage and animation data representing changes over time of scene geometry elements, but also images can be modified to include shading that is a function of positions of objects at other than the current instantaneous time for a frame render such that the motion effect shading would suggest motion of at least one of the elements to a viewer of the generated images. Motion effects provide, based on depiction parameters and/or artist inputs, shading that varies for at least some received animation data, received motion depiction parameters, for at least one pixel, a pixel color is rendered based on motion effect program output and at least some received scene geometry, such that the output contributes to features that would suggest the motion.
