Patent number: 11523004Abstract: An example of an apparatus including a communication interface to receive an image file is provided. The image file represents a scanned image of a output generated by a printing device. The apparatus further includes an identification engine to process the image file with a convolutional neural network model to identify a feature. The feature may be indicative of a potential failure. The apparatus also includes an image analysis engine to indicate a life expectancy of a part associated with the potential failure based on the feature. The image analysis engine uses the convolutional neural network model to determine life expectancy.Type: GrantFiled: September 21, 2018Date of Patent: December 6, 2022Assignees: Hewlett-Packard Development Company, L.P., Rochester Institute of TechnologyInventors: Darrel D.

Patent number: 8515171Abstract: A multi-resolution color image segmentation algorithm which takes advantage of gradient information in an adaptive and progressive framework is described. A gradient-based segmentation method is initiated with a dyadic wavelet decomposition scheme of an arbitrary input image, accompanied by a vector gradient calculation of its color converted counterpart. The resultant gradient map is used to automatically and adaptively generate thresholds for segregating regions of varying gradient densities, at different resolution levels of the input image pyramid. In combination with a confidence map and non-linear spatial filtering techniques, regions of high confidence are passed from one resolution level to another until the final segmentation at highest (original) resolution is achieved.Type: GrantFiled: January 11, 2010Date of Patent: August 20, 2013Assignees: Rochester Institute of Technology, Hewlett-Packard Development Company, LPInventors: Sreenath Rao Vantaram, Eli Saber, Sohail Dianat, Mark Shaw, Ranjit Bhaskar

Publication number: 20090080773Abstract: A method for segmenting an image receives the image. The image has a number of pixels and a number of color channels. The image is initially segmented into a number of initial regions at least by dynamically selecting a plurality of seeds within the image using a dynamic color gradient threshold and growing the initial regions from the seeds until the initial regions encompass all the pixels of the image. A texture channel of the image is generated at least by applying an entropy filter to each of a plurality of quantized colors of the image. The initial regions into which the image has been initially segmented are multimodal-merged based on the color channels and the texture channel of the image, to yield a number of merged regions corresponding to segmentation of the image.Type: ApplicationFiled: September 20, 2007Publication date: March 26, 2009Inventors: Mark Shaw, Ranjit Bhaskar, Luis Garcia Ugarriza, Eli Saber, Vincent Amuso

Reflectance values are obtained from the first and second test patches. A set of gray balanced tone reproduction curves are obtained based on the reflectance values of the first test patches, and a set of spatial gray balanced tone reproduction curves are obtained based on the reflectance values of the second test patches.Type: GrantFiled: January 15, 2003Date of Patent: November 13, 2007Assignee: Xerox CorporationInventors: Lalit K.

Publication number: 20050129328Abstract: A method for sharpening the corners of digital image data within an anti-aliasing image path so as to overcome corner rounding when displayed or printed. The method comprises stepping a window across the image data and comparing that windowed data to templates or performing Boolean logic and arithmetic operations on the image data. Upon determining a match or a corner detection, pixel values are substituted in the identified pixel locations to achieve a clustering of the substituted pixel values about the corner structure producing a corner-enhanced digital image. Filtering and sampling are then performed according to an anti-alias operation to the corner-enhanced image to produce an anti-aliased corner enhanced image. The data substitution will achieve a localized clustering or “ear” of toner/ink, or in the alternative for inside corners the localized clustered absence of toner/ink. The result of this clustering is a sharpening of the corners so that they display or print as intended by the bitmap.Type: ApplicationFiled: December 15, 2003Publication date: June 16, 2005Inventors: Eli Saber, Robert Loce
