摘要： Methods, apparatus, and computer-readable storage media for subspace video stabilization. A subspace video stabilization technique may provide a robust and efficient approach to video stabilization that achieves high-quality camera motion for a wide range of videos. The technique may transform a set of input two-dimensional (2D) motion trajectories so that they are both smooth and resemble visually plausible views of the imaged scene; this may be achieved by enforcing subspace constraints on feature trajectories while smoothing them. The technique may assemble tracked features in the video into a trajectory matrix, factor the trajectory matrix into two low-rank matrices, and perform filtering or curve fitting in a low-dimensional linear space. The technique may employ a moving factorization technique that is both efficient and streamable.

摘要： Three dimensional models corresponding to a target image and a reference image are selected based on a set of feature points defining facial features in the target image and the reference image. The set of feature points defining the facial features in the target image and the reference image are associated with corresponding 3-dimensional models. A 3D motion flow between the 3-dimensional models is computed. The 3D motion flow is projected onto a 2D image plane to create a 2D optical field flow. The target image and the reference image are warped using the 2D optical field flow. A selected feature from the reference image is copied to the target image.

摘要： Embodiments of a system and method for seeding rule-based machine learning models include generating a set of seed rules including one or more rules resulting from one or more previously performed machine learning operations and one or more randomly or pseudo-randomly generated rules. Embodiments may include performing one or more machine learning operations on the set of seed rules to generate a new set of rules for determining whether a pair of information items have a specific relationship. Generating the new set of rules from the seed rules may be faster than generating a set of rules from random data. Embodiments may also include applying the new set of rules to one or more pairs of information items to identify at least one pair of information items as having the specific relationship. For instance, the rules may be applied to identify pairs of information items that are duplicate pairs.

摘要： Methods and apparatus for robust video stabilization. A video stabilization technique applies a feature tracking technique to an input video sequence to generate feature trajectories. The technique applies a video partitioning technique to segment the input video sequence into factorization windows and transition windows. The technique smoothes the trajectories in each of the windows, in sequence. For factorization windows, a subspace-based optimization technique may be used. For transition windows, a direct track optimization technique that uses a similarity motion model may be used. The technique then determines and applies warping models to the frames in the video sequence. In at least some embodiments, the warping models may include a content-preserving warping model, a homography model, a similarity transform model, and a whole-frame translation model. The warped frames may then be cropped according to a cropping technique.

摘要： Methods and apparatus for temporal matte filtering. Temporal matte filtering methods are described that improve the temporal coherence of alpha mattes for a video sequence while maintaining the matte structures on individual frames. The temporal matte filter may implement a level-set-based matte averaging method. In the level-set-based matte averaging method, two or more input alpha mattes are obtained. Level set curves are generated for the two or more alpha mattes. An averaged level set is computed from the two or more level sets according to a distance-transform-based technique. A temporally smoothed alpha matte may then be reconstructed by interpolating pixel alpha values between the inner and outer level set curves of the averaged level set. The alpha mattes can be optionally warped towards a center frame according to an optical flow technique before the averaging operation performed by the temporal matte filter.

摘要： The disclosure is directed to a method of making yttrium oxide, Y2O3, coatings on substrates suitable for use at infrared wavelengths, including use in the 2-12 μm range. The coating method eliminates or substantially eliminates the absorptions peaks that typically appear at approximately 3.0 μm, 6.6 μm and 7.1 μm. This is achieved by using Y metal as the yttrium source in combination with an oxygen-containing plasma to form the Y2O3, coating in place of the using Y2O3 as the coating material source The disclosure is further directed to optics suitable for use in the infrared that have such coatings. The transmission spectrum of the coated substrate made according to the method described herein is greater than the transmission spectrum of the uncoated substrate over the wavelength range of 4 μm to 12 μm.
