Abstract: Embodiments of the present invention provide a system for performing image conversion operations. The system starts by receiving a request from a client for one or more pixel buffers containing a pixel-formatted, cropped, geometrically transformed, and/or color matched version of an image representation. The system then determines if a provider can provide the one or more pixel buffers. If so, the system calls the provider to generate the one or more pixel buffers containing the pixel-formatted, cropped, geometrically transformed, and/or color matched version of the image representation. Otherwise, the system calls the provider to generate one or more intermediate pixel buffers, generates a sequence of converters for converting the one or more intermediate pixel buffers, and calls the sequence of converters to generate the one or more pixel buffers containing the pixel-formatted, cropped, geometrically transformed, and/or color matched version of the image representation.

Abstract: To facilitate rendering an image, e.g., a portion of a PDF page, at higher resolutions or locations than could be expressed using standard 32 bit fixed point integer values, an image is segmented and a user space coordinate system origin used for individual segment processing is transformed on a per segment basis to each segment locality before a render request is made to a rendering function library. After a new origin of a segment is established, the PDF page content contained within that locality corresponding to the individual segment being processed is rendered, e.g., using functions available in the PDF software library. The results of processing the segments is combined to produce a final high-resolution image. While the input to the rendering process may include values which can not be expressed in 32 bit fixed point notation, the segmentation process allows the individual segments to be rendered using rendering specified using such notation.

Abstract: This invention deals with a morphological genome for design applications. This genome encodes all forms. It comprises a finite set of morphological genes, where each gene specifies a distinct group of morphological transformations defined by a group of independent topological, geometric or other parameters. The morph genes and their parameters are mapped within an integrated higher-dimensional framework with each parameter represented along an independent vector in higher-dimensional Euclidean space. Each distinct number associated with a parameter or a group of parameters is represented by a distinct point in this space referenced by its higher-dimensional Cartesian co-ordinates which represent the genetic code for the specific form being mapped. The morph genome can be used as an interactive design tool to generate known and new forms for applications in all design fields as well as for fabricating these forms when linked with digital fabrication devices within an integrated computational environment.

Abstract: Although GPUs have been harnessed to solve non-graphics problems, these solutions are not widespread because GPUs remain difficult to program. Instead, an interpreter simplifies the task of programming a GPU by providing language constructs such as a set of data types and operations that are more familiar to non-graphics programmers. The interpreter maps these familiar language constructs to the more difficult graphics programming resources such as DirectX®, OpenGL®, Cg®, and/or HLSL®.

Global alignment values are determined for all images at corresponding pairs of adjacent image positions of each frame based on the local alignment values for the images at the corresponding pair of adjacent image positions of each frame. Each global alignment value is applied to at least one image of the images of the corresponding pair of adjacent image positions of each frame.

Abstract: A distortion corrected panoramic vision system and method provides a visually correct composite image acquired through wide angle optics and projected onto a viewing surface. The system uses image acquisition devices to capture a scene up to 360° or 4? steradians broad. An image processor corrects for luminance or chrominance non-uniformity and applies a spatial transform to each image frame. The spatial transform is convolved by concatenating the viewing transform, acquisition geometry and optical distortion transform, and display geometry and optical transform. The distortion corrections are applied separately for red, green, and blue components to eliminate lateral color aberrations of the optics. A display system is then used to display the resulting composite image on a display device which is then projected through the projection optics and onto a viewing surface. The resulting image is visibly distortion free and matches the characteristics of the viewing surface.

Abstract: An image transformation method for translating a non-linear 2D geometrical transformation into two separable 1D geometrical transformations first determines the inverse of the 2D geometrical transformation to form an inverse 2D geometrical transformation. Then the method converts the inverse 2D geometrical transformation into an analytical inverted 2D geometrical transformation and separates the analytical inverse 2D geometrical transformation into first and second 1D geometrical transformations. The method then represents said inverse 2D geometrical transformation and first and second 1D geometrical transformations as tensor spline surfaces and then compares an evaluation of said first and second 1D geometrical transformations at each pixel with an evaluation of the analytical inverse 2D geometrical transformation at each pixel. If the error evaluation does not meet a predetermined level of performance then the separation and transformation steps are repeated.
