20080298704 | FACE AND SKIN SENSITIVE IMAGE ENHANCEMENT - Systems and methods of face and skin sensitive image enhancement are disclosed. In one aspect, a face map that includes for each pixel of an input image a respective face probability value indicating a degree to which the pixel corresponds to a human face is calculated. A skin map that includes for each pixel of the input image a respective skin probability value indicating a degree to which the pixel corresponds to human skin is ascertained. The input image is enhanced with an enhancement level that varies pixel-by-pixel in accordance with the respective face probability values and the respective skin probability values. In another aspect, a facial content measurement value indicating a degree to which an input image contains human face content is ascertained. A tone-correction process is tuned in accordance with the facial content measurement value. The input image is enhanced in accordance with the tuned tone-correction process. | 12-04-2008 |
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 |

20120117565 | VIRTUAL-MACHINE-BASED APPLICATION-SERVICE PROVISION - Embodiments of the present invention are directed to application-service provision by application-service-provider centers to remote application-service consumers, including small businesses, medium-sized businesses, and other similarly-sized institutions and organizations, as well as to users of individual computers, such as home computers. Rather than executing applications at an application-service-provider center, the applications are instead distributed to remote client sites for execution by virtual machines controlled and managed by an application-service-provider center. Execution of the applications by virtual machines at remote client sites alleviates constraints and bottlenecks associated with communications between client computers and remotely executing applications, while providing management capabilities and security that allow the application-service center to manage application execution as if the remotely executing applications were executing within the application-service center. | 05-10-2012 |

20120182587 | METHOD AND SYSTEM FOR ENHANCING A DIGITAL HALFTONE REPRESENTATION FOR PRINTING - A method for predicting an appearance of a rendering by a printer of a digital halftone representation of a continuous-tone image includes calculating a predicted absorptance value of a dot of a rendered halftone of the digital halftone representation. The dot corresponds to a pixel of the digital halftone representation. The predicted absorptance value is based on a configuration of pixel values of pixels in an immediate neighborhood of the pixel, and on a weighted contribution of a pixel value of each pixel in an outer neighborhood of the pixel. The method may be incorporated into a halftoning technique. Relating computer program product and data processing system are also disclosed. | 07-19-2012 |
20120188611 | COLOR SCREEN SETS - A method for designing a screen set for color halftoning includes selecting a screen set that includes at least two screens. The screens are applied to a uniform color image so as to form a set of corresponding colorant halftones. The colorant halftones are superposed to form a color halftone. A spatial frequency spectrum of the color halftone is calculated. Maxima of the spatial frequency spectrum that occur at two effective frequencies are identified, the two effective frequencies being located in two adjacent quadrants of a complex spatial frequency space. A magnitude of each effective frequency is compared with a predetermined frequency magnitude. The screen set is accepted for future application for color halftoning only if both effective frequency magnitudes are greater than the predetermined frequency magnitude. Relating computer program product and data processing system are also disclosed. | 07-26-2012 |
