    摘要： Systems, methods, and apparatuses are described for providing one or more optimized functions for image processing and/or signal processing. Some exemplary methods described include receiving a media input and performing a first function of a staged computation on the media input to generate a result, the result comprising a constant value. Using the result, a second function of the staged computation may be compiled. The second function may correspond to inputs between a first value and a second value inclusive of the constant value. The second function may be performed to generate a media output.

    摘要： A technique for solving an inverse-kinematic problem by interpolating solutions from examples. Example poses or motions of an object are collected and annotated. The annotations are essentially parameters for a function—i.e., the function X(p) generates degree-of-freedom values of an object that is posed in a manner that satisfies parameters p. The analytic function X is interpolated from these examples and improved automatically based on kinematic measurements. Preferably, the interpolation is created by taking a weighted sum of cardinal basis functions having linear and radial parts, Preferably, the interpolation is a weighted sum of cardinal basis functions having linear and radial portions.

    摘要： A system for providing improved computer animation can be used in interactive applications such as 3D video games and virtual environments. Tie system comprises an offline authoring system with tools for constructing controllable “verbs” from sets of motion example segments, and for constructing transitions between different verbs; and a runtime system for controlling the invocation of the verbs as parameterized by user defined “adverbs”. The system involves interpolating predefined animation segments created by an animator or through motion capture video. The animation segments are made up of data representing selected points on the animated creature (e.g., the joints and extremities) and values, as a function of time, for each degree of freedom of those points. In addition, a “verb graph” is constructed to act as the glue to assemble verbs and their adverbs into a runtime data structure. The verb graph defines the allowable transitions from one verb to another verb. A set of “keytimes” is also defined. The keytimes are instances when important structural events occur, and are used to pre-process the motion examples into a synchronized (canonical) time frame for interpolation.

    摘要： An analysis module accesses an input image, identifies an algorithm to be used to generate an output image from the input image, analyzes the algorithm, and determines a pixel offset of the algorithm. A generation module identifies a region of the output image in which output pixels are to be generated without an edge-checking operation. The generation module generates a modified version of the algorithm that omits the edge-checking operation and generates the output image by using the modified version to generate output pixels in the identified region.

    摘要： Modern animation and modeling systems enable artists to create high-quality content, but provide limited support for interactive applications. Although complex forms and motions can be constructed either by hand or with motion or geometry capture technologies, once they are created, they are difficult to modify, particularly at runtime. Interpolation provides a way to leverage artist-generated source material. Presented here are methodologies for efficient runtime interpolation between multiple forms or multiple motion segments. Radial basis functions provide key mathematical support for the interpolation. Once the illustrated and described system is provided with example forms and motions, it generates a continuous range of forms referred to as a “shape” or a continuous range of motions referred to as a verb. Additionally, shape interpolation methodology is applied to articulated figures to create smoothly skinned figures that deform in natural ways. The runtime interpolation of the forms or motions runs fast enough to be used in interactive applications such as games.
