摘要： Polynomial approximation based image filter methods, systems, and machine-readable media are described. In one aspect, multiple n-order polynomial approximations to a value of a target pixel of an input image are computed from multiple respective sets of m values of pixels in a neighborhood of the target pixel, wherein n≧0 and m≧n+1. A respective approximation error is computed from each of the computed n-order polynomial approximations. A value of a pixel of an output image is computed from the target pixel value and the computed approximation errors.

摘要： A first representation [102] of an intended location for a print product is received [202]. A position within the first representation [102] for the print product is then determined [204]. A perspective matrix for warping an image of the print product into the first representation is automatically determined [206]. The image of the print product is warped [208] into the first representation [102] based on the perspective matrix to achieve a second representation [124] of the intended location. The second representation [124] includes the first representation [102] with a placement of the print product therein. The second representation [124] is then displayed [210].

摘要： First, second, and third image planes are obtained from at least one image sensor. The first image plane is formed from light of a first spectral distribution. The second image plane is formed from light of a second spectral distribution. The third image plane is formed from light of a spectral distribution which substantially covers the visible spectrum. First spatial frequency components are generated from the first, second and third image planes. A second spatial frequency component is generated from the third image plane. A color transform is applied to the first spatial frequency components from the first, second, and third image planes to obtain at least first, second and third transformed first spatial frequency image planes. The at least first, second and third transformed first spatial frequency image planes are combined with the second spatial frequency component from the third image plane to form an image.

摘要： Processing of a mosaic digital image includes interpolating values of a first color at pixels where the first color was not sampled. The interpolation of the first color value at a given pixel includes determining likelihoods of the given pixel belonging to the same region as each of at least two other pixels having sampled values of the first color. The other pixels are in different directions relative to the given pixel. The interpolation further includes using the likelihoods and the sampled values of the other pixels to interpolate the first color at the given pixel.

摘要： Upscaling of an anti-aliased graphical element in a raster image includes generating a grid of pixels. Resolution of the grid is higher than resolution of the graphical element. Each pixel in the anti-aliased graphical element corresponds to a group of pixels in the higher resolution grid. The upscaling further includes distributing coverage of each transition pixel in the anti-aliased graphical element to the corresponding pixels in the higher resolution grid. The coverage is distributed unevenly.

摘要： Method embodiments of the present invention provide for semi-automated or fully automated assessment of the quality of device-rendered text, including graphical symbols, characters, and other printable or displayable patterns. Method embodiments of the present invention employ one or more metrics that involve the comparison of input characters, including text characters, symbols, and character-like graphics, with corresponding digital output characters obtained by capturing images of characters rendered by a character-rendering device. The one or more metrics include individual computed relative entropy APQi metrics, reflective of differences in character-to-character distance distributions between one input character c, and the set of input characters c*, a cumulative computed relative entropy APQ, stroke irregularity, contrast measure, sharpness, and background uniformity. These individual metrics can be computed and stored separately as well as output to a user of a character-rendering-quality measurement system, or may be combined together in various ways to produce one or more comprehensive, cumulative metrics for storage and output.
