Abstract: Local histogram and local histogram-based functions can be determined by generating offset-kernel images based on domain-shifted tonal filter kernels. The offset-kernel images can be reused for multiple image locations and/or local neighborhood sizes, shapes, and weights. A neighborhood filter representing the desired local neighborhood size, shape, and frequency domain characteristics is applied to each of the offset-kernel images. Neighborhood filters may include a temporal dimension for evaluating neighborhoods in space and time. Neighborhood filtered offset-kernel images' values represent samples of local histogram or local histogram-based function corresponding with the domains of their associated domain-shifted tonal filter kernels. Arbitrary functions may be used as tonal filter kernels. A histogram kernel may be used to sample values of local histogram functions.

Abstract: Variable motion blur is created by varying the evaluation time used to determine the poses of objects according to motion blur parameters when evaluating a blur frame. A blur parameter can be associated with one or more objects, portions of objects, or animation variables. The animation system modifies the time of the blur frame by a function including the blur parameter to determine poses of objects or portions thereof associated with the blur parameter in a blur frame. The animation system determines the values of animation variables at their modified times, rather than at the time of the blur frame, and poses objects or portions thereof accordingly. Multiple blur parameters can be used to evaluate the poses of different portions of a scene at different times for a blur frame. Portions of an object can be associated with different blur parameters, enabling motion blur to be varied within an object.

Abstract: Test patterns and associated techniques for testing the fidelity of intensity reproduction are disclosed. One set of embodiments provide test patterns that incorporate anti-aliased features such as anti-aliased edges or lines. In various embodiments, these anti-aliased features expose undesirable, nonlinear transformations of the test patterns by one or more devices in an image output system or chain. Using these test patterns, users may more easily evaluate the end-to-end gamma response of the system, and may more easily calibrate gamma controls accordingly. Additionally, users may more easily identify nonlinear image resampling performed in gamma, rather than linear, space.

Abstract: A system and method for characterizing and adjusting an offset between displayed stereo image pairs allows for calibration of the stereo image content for each display environment. The stereo image content is typically authored assuming a particular display image size. When the stereo image content is displayed in a display environment that does not conform to the particular display image size the offset between displayed stereo image pairs is increased or decreased, resulting in a viewing experience that is different than intended. In some cases, the viewer may experience discomfort due to eye strain or eye fatigue. Adjusting the offset during the playback of the stereo image content may improve the viewer experience.
