    摘要: A method and apparatus for image stabilization takes an input image sequence including a plurality of frames, estimates frame-level motion vectors for each frame, and adaptively integrates the motion vectors to produce, for each frame, a motion vector to be used for image stabilization. A copy of the reference image of a frame is displaced by the corresponding adaptively integrated motion vector. In one embodiment, the perimeter of the image sensor is padded with a margin to be used for image compensation. In another embodiment, vertical and horizontal components are treated independently. In still another embodiment, the motion estimation circuitry associated with an MPEG-4 encoder is used to calculate macroblock level vectors, and a histogram is used to compute a corresponding frame-level vector for that frame.

    摘要: In general, the disclosure describes various techniques for providing edge-directed scaling filters that may be used to scale image data. An example device includes a storage medium configured to store a first lookup table and a second lookup table, and one or more processors configured to obtain one or more gradient values that each indicates a gradient between values of at least two pixels in a source image. The one or more processors are also configured to generate one or more inverse gradient values from a first lookup table based on the gradient values, and to generate one or more edge-directed scaling filter coefficients from a second lookup table based on the inverse gradient values. The one or more processors may be further configured to generate an edge-directed filter based on the coefficients, and to apply the filter to the at least two pixels to generate an interpolated pixel.

    摘要: Techniques for performing mesh-based video compression/decompression with domain transformation are described. A video encoder partitions an image into meshes of pixels, processes the meshes of pixels to obtain blocks of prediction errors, and codes the blocks of prediction errors to generate coded data for the image. The meshes may have arbitrary polygonal shapes and the blocks may have a predetermined shape, e.g., square. The video encoder may process the meshes of pixels to obtain meshes of prediction errors and may then transform the meshes of prediction errors to the blocks of prediction errors. Alternatively, the video encoder may transform the meshes of pixels to blocks of pixels and may then process the blocks of pixels to obtain the blocks of prediction errors. The video encoder may also perform mesh-based motion estimation to determine reference meshes used to generate the prediction errors.

    摘要: A method and apparatus for animation of an object. The invention includes communication destination matrixes used for project source and destination vertex arrays of, source and destination objects from an original space to an ortho-normal space. At a receiver (200), a control system (210) transforms zero-mean of source and destination vertex arrays using, respectively, the source and destination projection matrixes. Control system (210) computes an interim vertex array in the ortho-normal space based on a linear interpolation of the transformed source and destination vertex arrays, and an interim projection matrix based on a linear interpolation of the source and destination projection matrixes. Control system (210) transforms the interim vertex array from the ortho-normal space to the original space based on the interim projection matrix. A display (250) displays an interim object based on the interim vertex array in an animation of the object.

    摘要: The techniques described in this disclosure are directed to interpolating pixel values. In some examples, the techniques interpolate a pixel value for an interpolated center pixel based on pixel values of pixel that reside on diagonal lines that are orthogonal to one another. The techniques may determine first order derivative values and, in some examples, second order derivative values to determine which pixels to utilize to interpolate the pixel values for the interpolated center pixel. The techniques may similarly determine pixel values for non-center interpolated pixels using orthogonal vertical and horizontal lines.

    摘要: The rendering of 3D video images on a stereo-enabled display (e.g., stereoscopic or autostereoscopic display) is described. The process includes culling facets facing away from a viewer, defining foreground facets for Left and Right Views and common background facets, determining lighting for these facets, and performing screen mapping and scene rendering for one view (e.g., Right View) using computational results for facets of the other view (i.e., Left View). In one embodiment, visualization of images is provided on the stereo-enabled display of a low-power device, such as mobile phone, a computer, a video game platform, or a Personal Digital Assistant (PDA) device.
