| 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 |
| 20090128616 | APPARATUS AND METHOD OF REDUCING BANDING ARTIFACT VISIBILITY IN A SCANNING APPARATUS - A method of, and apparatus for, reducing the visibility of banding artifacts on a printed medium comprising producing synthetic artifacts on the printed medium, overlapping scan lines at swath boundaries and controlling exposure along a scan line to reduce the visibility of the banding artifacts. | 05-21-2009 |
| 20100003045 | ELECTROGRAPHIC DOT GAIN AND OPTICAL DENSITY DECOUPLING METHOD, XEROGRAPHIC IMAGE REPRODUCTION, AND SYSTEMS, METHODS AND SOFTWARE RELATED THERETO - 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. | 01-07-2010 |

| 20110090537 | SCREEN DESIGN FOR PROCESS VARIATION ARTIFACT REDUCTION - In a method for designing a halftone screen configured to reduce artifacts in a printed image, artifacts due to a process variation resulting from printing of the image through use of a halftone screen design are modeled and the halftone screen is designed to have threshold values that substantially reduce the artifacts due to the process variation. | 04-21-2011 |
| 20110131551 | GRAPHICAL USER INTERFACE INPUT ELEMENT IDENTIFICATION - Systems, methods, and other embodiments associated with graphical user interface input element identification are described. One example system identifies a graphical user interface (GUI) element through which an input to an application was received based on comparing images generated from data provided by the application. Data that describes the GUI element may then be provided. | 06-02-2011 |
