20100303306 | METHOD AND SYSTEM FOR MEASURING TEXT-RENDERING QUALITY - 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. | 12-02-2010 |

20090034870 | Unified spatial image processing - Various embodiments of the present invention are directed to methods and systems for image processing that are unified in nature, carrying out many image-enhancement tasks together in a unified approach, rather than sequentially executing separately implemented, discrete image-enhancement tasks. In addition, the methods and systems of the present invention can apply image-enhancement to local, spatial regions of an image, rather than relying on global application of enhancement techniques that result in production of artifacts and distortions. In certain embodiments of the present invention, various different types of intermediate images are produced at each of a number of different scales from a received, input image. From these intermediate images, a photographic mask and temporary image are obtained, and the photographic mask and temporary image are then employed, along with a look-up table or function that receives values from the photographic mask and temporary image, to compute an enhanced, output image. In a described embodiment of the present invention, the intermediate images include low-pass, band-pass, photographic-mask, and temporary-image intermediate images computed at each of a number of different scales. | 02-05-2009 |
20090034871 | Method and system for enhancing image signals and other signals to increase perception of depth - Various embodiments of the present invention are directed to methods and systems for processing signals, particularly signals encoding two-dimensional images, such as photographs, video frames, graphics, and other visually displayed information. Rather than attempting 3D-boosting by attempting a global contrast enhancement, method and system embodiments of the present invention generate a soft-segmented image that is separately contrast enhanced, segment-by-segment, to produce an enhanced soft-segmented image. A details image is then computed, and is combined with the enhanced soft-segmented image to produce an intermediate image, the brightness of which is adjusted to produce a 3D-boosted output image. Local contrast enhancement provides for proportional enhancement of homogenous regions, resulting in 3D-boosting without introduction of anomalies, artifacts, and distortion. | 02-05-2009 |
20090110323 | Method and system for dual-envelope image enhancement - Various embodiments of the present invention are directed to methods and systems for processing signals, particularly signals encoding two-dimensional images, such as photographs, video frames, graphics, and other visually displayed information. In various method embodiments of the present invention, an input image signal is decomposed into an upper-envelope function, a lower-envelope function, and a details function. One or both of the upper-envelope and lower-envelope functions are then modified to produce one or more image-enhancing effects when the modified upper-envelope and lower-envelope functions are recombined with the details function to produce an enhanced image signal. | 04-30-2009 |

20100266212 | Estimating Vanishing Points in Images - 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. | 10-21-2010 |
20110013837 | HIERARCHICAL RECURSIVE IMAGE SEGMENTATION - An image is segmented into image regions. Each of the image regions is represented by a respective vertex. A graph of the vertices interconnected by edges, each of which has a respective edge weight value, is built. The graph is partitioned into respective disjoint subgraphs based on the edge weight values. The partitioning of one or more of the subgraphs into respective subgraphs is repeated. A partition tree data structure that describes a partitioning hierarchy of parent-child relationships between the subgraphs is produced. | 01-20-2011 |
20120029880 | METHOD AND SYSTEM FOR DETERMINING A SPECTRAL VECTOR FROM MEASURED ELECTRO-MAGNETIC-RADIAION INTENSITIES - Embodiments of the present invention are directed to determining the spectral vector of electromagnetic radiation reflected from, transmitted through, or emitted from a sample using a set of n intensity measurements. In general, the spectral vector has a dimension k that is greater than the number of measured intensities n. However, in many cases, the physical and chemical constraints of a system, when properly identified and modeled, effectively reduce the number of unknowns, generally the k components of the spectral vector, to an extent that allows for the spectral vector to be characterized from a relatively small number n of measured intensities. | 02-02-2012 |

20140340697 | DETERMINING NEW COLOR VALUES OF AN IMAGE BASED ON AN ACITIVITY MAP - A method comprises computing an activity map for an input image. The activity map indicates an amount of variable spatial activity in the input image. The method further comprises producing an output image based on the activity map, and controlling a printhead to cause the output image to be printed. The output image contains a plurality of color pixels and each such color pixel is represented by at least one of cyan (C), magenta (M), yellow (Y), and black (K) in a color space. | 11-20-2014 |
