Abstract: Systems and methods for translating time-stamped events to performance indicators are provided. A data component can receive sequences of time-stamped events associated with a device with a set of subsystem components. A conversion component can convert the sequences to time series based upon log transformations of event-intervals associated with the events. An estimation component can estimate local event-descriptor distribution characteristics at an event count associated with the time series. A translation component can translate the local event-descriptor distributions characteristics into performance indicators.

Abstract: Disclosed herein are techniques for formulating parsing rules. Substrings are detected in an input data. Each substring is associated with a semantic token that categorizes each substring. Patterns of semantic tokens are identified. Rules for parsing the input data are formulated based at least partially on the patterns of semantic tokens.

Abstract: A project management system (10) and method (250) are included. The project management system (10) includes a production database (14) in memory (15) to store project data (20). The project data (20) can include workflow resource data (16) describing workflow resources (54, 56) and feedback data (17) obtained for each workflow step (52) of a plurality of projects (18) of a project type (152). The project management system (10) also includes a processor (27) to access the memory (15) and to execute computer readable instructions including a production learning module (26) to analyze the workflow resource data (16) and the feedback data (17) to generate predictive project data (12). The predictive project data (12) can describe a predicted workflow (154) for a given project (18) of the project type (152) based on the workflow resources (54, 56).

Abstract: A method for estimating three-dimensional structure from a two-dimensional image (502) includes obtaining first and second vanishing points (120, 122); comparing image patches (202) along first and second virtual lines (204, 208) extending from the first and second vanishing points (120, 122), respectively, and through a pixel; generating values for each of the first and second virtual lines (204, 208) based on the comparison of the image patches (202); accumulating the values for each the pixel in the two-dimensional image (502); and determining a corner pixel (106) based on a highest of the accumulated values.

Abstract: A designer-adaptive visual code (32, 32?, 32?) includes a user-selected set glyphs (36, 36?, 36?, 36??), a user-selected set of allowable glyph orientations relative to a user-selected reference angle, and a user-selected spatial arrangement of the glyphs (36, 36?, 36?, 36??). The user-selected set of glyphs (36, 36?, 36?, 36??) has a size sufficient to recover geometric characteristics of at least one repeating code portion so as to generate an analyzable image when captured via a camera-equipped mobile device (26). The user-selected spatial arrangement of the glyphs (36, 36?, 36?, 36??) includes the at least one repeating code portion (34) to be visible on a surface from at least two different areas of the surface.

Abstract: An output image that corresponds to a higher-resolution version of a source image is produced. In this process, source pixels of the source image are processed with a set of linear non-separable filter kernels to produce the output image with a corresponding output pixel block of constituent output pixels for each of the source pixels. The set of filter kernels has a mean substantially equal to an identity filter such that a downscaling of the of the output image to a resolution level of the source image produces a downscaled image that is substantially identical to the source image. For each of the source pixels, each of the filter kernels in the set is applied to a local neighborhood of the source pixel to produce a respective value of each of the constituent output pixels of the corresponding output pixel block.

Abstract: A digital image is processed to provide an estimation of the position in the image plane of a vanishing point. The processing includes detecting pairs of similar image patches and identifying a concurrent set of straight virtual lines that substantially converge at a point on the image plane, each line passing through a pair of similar image patches within the image.

Abstract: A scanning device includes a scanning mechanism and a processing mechanism. The scanning mechanism scans an image fixed on a medium to generate a digital infrared representation of the image and a digital visible light representation of the image. The processing mechanism substantially reduces effects of noise and distortions within the digital visible light representation of the image in one pass. The processing mechanism at least decorrelates visible light aspects from the infrared representation of the image and employs a one-pass filter that uses both the infrared and the visible light representations of the image.

Abstract: A method is provided for decoupling the control of dot gain and optical density in electrophotographic based printing by varying the exposure level for each dot in an image.

Abstract: In a method for processing an input image to reduce compression-related artifacts, a plurality of block transforms of the input image having respective plurality of block-grid locations are generated, where each of the block-grid locations is shifted with respect to the block-grid locations in each of the other block transformed images. In addition, a plurality of respective intermediate transform domain filtered images having modified transform coefficients are generated. Per-pixel relative weights are assigned to each of the intermediate transform domain filtered images, where each of the intermediate transform domain filtered images has different contexts, and where the per-pixel relative weights are adaptive to the local context in each of the intermediate transform domain filtered images.

Abstract: A method for processing an image using a bilateral filter. The bilateral filter is reformulated at each pixel location in the image into a sum of the original signal value of a central pixel at said pixel location and a bilateral correction term which is a function of local signal differences between the central pixel and its neighbors. The bilateral correction term is calculated using a computationally efficient approximation.

Abstract: Representations of an input signal at different lower resolutions are obtained, where n denotes a level of resolution, and where 0?n?N. Level n=N corresponds to the representation having the lowest resolution, and level n=0 corresponds to the input signal. The resolution increases as level n decreases. The nth level representation is used to estimate and remove low frequency error in the n?1th level representation. Then application-specific processing is performed on the n?1th level representation.
