Patent number: 7844118Abstract: Disclosed herein is a method for detecting thin lines in image data. The method is performed by a processor to process contone image data. The processing includes combining a first result of thin line detection using a first method and a second result of thin line detection using a second method to produce an improved thin line determination in the image data. The methods include processing and thresholding in the contone and binary domain to determine if a thin line exists in the window of image data. The thin line determination may also be merged with the image data as processed using other image segmentation techniques. The disclosed method produces better quality output images and reduces the addition of false lines in an image.Type: GrantFiled: July 1, 2009Date of Patent: November 30, 2010Assignee: Xerox CorporationInventors: Xing Li, Barbara Farrell, Peter McCandlish, Ryan Metcalfe

Patent number: 7844174Abstract: A method and system for additively, manually sequentially or manually in parallel, selecting multiple points or regions of interest in the analog or digital viewfinder of a photo or video camera with automatic controls like auto-focusing, auto-metering and auto white-balancing. Points or regions capable of being selected, within a grid of elements comprising a camera's evaluative matrix and represented to the user in a viewfinder or other display, may be hard-coded (pre-defined, selectable regions) or any point, pixel, or group of pixels. Data from the selected regions is used to simultaneously, dynamically adjust focus related parameters, light metering and white balancing of the camera and is tied into these features. Point selection may be via touch screen or by holding down a lock button.

Patent number: 7844117Abstract: An image digest based search approach allows images within an image repository related to a query image to be located despite cropping, rotating, localized changes in image content, compression formats and/or an unlimited variety of other distortions. In particular, the approach allows potential distortion types to be characterized and to be fitted to an exponential family of equations matched to a Bregman distance. Image digests matched to the identified distortion types may then be generated for stored images using the matched Bregman distances, thereby allowing searches to be conducted of the image repository that explicitly account for the statistical nature of distortions on the image. Processing associated with characterizing image noise, generating matched Bregman distances, and generating image digests for images within an image repository based on a wide range of distortion types and processing parameters may be performed offline and stored for later use, thereby improving search response times.Type: GrantFiled: September 7, 2007Date of Patent: November 30, 2010Assignee: Xerox CorporationInventor: Vishal Monga

Patent number: 7843616Abstract: What is disclosed is a novel system and method for background suppression in the image path. In one example embodiment, an image is scanned and RGB color values generated for each pixel. Each of the pixels is converted into a Lab color space to obtain luminance and chrominance values. A background luminance and a luminance variation are determined for the scanned image. For each pixel, a determination is made whether that pixel is a white pixel or a non-white pixel based. If the pixel is a white pixel, an adjustment chrominance value for that pixel is determined. The value of the chrominance adjustment is modulated as a function of a difference between the white pixel's luminance and the background luminance. The modulated chrominance adjustment is applied to the white pixel. Adjusted and non-adjusted pixels are stored in a memory. A printer controller converts the pixels to an output space.Type: GrantFiled: March 27, 2008Date of Patent: November 30, 2010Assignee: Xerox CorporationInventor: Xing Li
