Patent number: 9363419Abstract: Methods and systems receive an image-processing request relating to user images from a user. Such methods and systems classify the user images into user-request image-element categories. Such methods and systems also retrieve previously stored user-specific preferences for the user-request image-element categories from a computer storage, when the previously stored user-specific preferences for the user-request image-element categories are maintained in the computer storage. However, when the previously stored user-specific preferences for the user-request image-element categories are not maintained in (are absent from) the computer storage, such methods and systems obtain additional user-specific preferences for the user-request image-element categories. Such methods and systems can then processes the image-processing request by altering renditions of the user images according to the previously stored user-specific preferences and/or the additional user-specific preferences.Type: GrantFiled: May 10, 2013Date of Patent: June 7, 2016Assignee: Xerox CorporationInventors: Wencheng Wu, Edul N.

Patent number: 9185402Abstract: Methods and systems are disclosed for updating camera geometric calibration utilizing scene analysis. Geometric calibration parameters can be derived with respect to one or more cameras and selected reference points of interest identified from a scene acquired by one or more of such cameras. The camera geometric calibration parameters can be applied to image coordinates of the selected reference points of interest to provide real-world coordinates at a time of initial calibration of the camera(s). A subset of a video stream from the camera(s) can then be analyzed to identify features of a current scene captured by the camera(s) that match the selected reference points of interest and provide a current update of the camera geometric calibration parameters with respect to the current scene.Type: GrantFiled: April 23, 2013Date of Patent: November 10, 2015Assignee: Xerox CorporationInventors: Wencheng Wu, Edul N.

Patent number: 9179043Abstract: Methods and systems present, to a user, different versions of sample images. Each of the sample images is classified into at least one image-element category of multiple image-element categories. Such methods and systems request the user to select preferred versions of the sample images from the different versions of the sample images, and receive in response a user selection of preferred images. The methods and systems determine user-specific preferences for each of the image-element categories based on the user selection of the preferred images. The methods and systems receive an image-processing request relating to user images from the user, and classify the user images into the image-element categories. When processing the image-processing request, the methods and systems alter renditions of the user images according to the user-specific preferences for each image-element category.Type: GrantFiled: October 19, 2012Date of Patent: November 3, 2015Assignee: Xerox CorporationInventors: Wencheng Wu, Edul N.

Patent number: 9165352Abstract: Methods and systems receive a series of images and compare at least two of the images in the series of images to locate items that are in different positions to identify moving items. Such methods and systems further calculate a measure of the moving items within the series of images. Additionally, such methods and systems perform a continuously variable image correction to remove the moving items from the images to produce a series of corrected images. This “continuously variable image correction” increases the amount of image correction for a relatively higher measure of the moving items and decreases the amount of image correction for a relatively lower measure of the moving items, and does so continuously as the measure of the moving items changes within the series of images.Type: GrantFiled: June 10, 2013Date of Patent: October 20, 2015Assignee: Xerox CorporationInventors: Wencheng Wu, Edul N.

Patent number: 9060164Abstract: A method for determining a response to misalignment of a camera monitoring a desired area includes acquiring temporal related frames from the camera including a reference frame. A pixel location is determined of a reference object from the frames. Using the pixel location of the reference object, a displacement of the camera between a current frame and the reference frame is determined. For the displacement exceeding a first threshold, a new displacement of the camera is measured by introducing at least one additional object to a camera field of view and comparing the new displacement to a second threshold. For the new displacement not exceeding the second threshold, the camera is recalibrated using a determined pixel location and a physical location of the at least one additional object. For the new displacement exceeding the second threshold, notification is provided of a misalignment to an associated user device.Type: GrantFiled: September 12, 2012Date of Patent: June 16, 2015Assignee: Xerox CorporationInventors: Wencheng Wu, Edul N.

Publication number: 20150154669Abstract: A time based parking management method, system and processor-readable media. A video-based parking occupancy detection unit can operate in association with an image-assisted parking kiosk to provide an automatic parking-time monitoring element. An image with respect to a vehicle parked onsite (e.g., parking lot, street side parking, etc.) can be captured via an image-capturing unit associated with the video-based parking occupancy detection unit and/or the image-assisted parking kiosk. The vehicle can be identified based on input provided to a GUI associated with the parking kiosk with said image displayed to initiate a parking session. A parking fee can be calculated based on the actual time parked and payment can be made by at least one payment mode after said parking session terminates.Type: ApplicationFiled: December 3, 2013Publication date: June 4, 2015Applicant: Xerox CorporationInventors: Wencheng Wu, Edul N.

Patent number: 8962065Abstract: Disclosed is a composite security element and a method for applying the same to a substrate (e.g., paper). The composite security element has a first pattern mark and a second pattern mark. The first pattern mark is marked in first (active) marking material (e.g., ink) and the second pattern mark is marked in second (passive) marking material. When exposed to light or radiation at wavelengths in the visible spectrum, the first and second pattern marks are indistinguishable from one another (to a naked human eye). When exposed to radiation at least some wavelengths outside of the visible spectrum, the first and second pattern marks are distinguishable from one another (e.g., first pattern reacts to non-visible light). The first pattern mark may be a security mark or symbol, for example. The marking materials may be colorless. Both first and second pattern marks are also associated with similar gloss.Type: GrantFiled: March 29, 2011Date of Patent: February 24, 2015Assignee: Xerox CorporationInventors: Edul N.

Publication number: 20150051461Abstract: What is disclosed is a system and method for performing a medical diagnosis for a subject of interest using a RGB video camera and a spot radiometer in a non-contact, remote sensing environment. In one embodiment, video images are captured using a RGB video camera in real-time of a subject of interest for medical diagnostic purposes. The video images are analyzed to identify a region of exposed skin for which measurements are desired to be obtained. A relative position of a spot radiometer is then adjusted such that the spot radiometer can measure incident radiation at a desired wavelength range from the identified region of exposed skin. The measurements are then used to perform a medical diagnosis for the subject. Various embodiments are disclosed.Type: ApplicationFiled: August 16, 2013Publication date: February 19, 2015Applicant: XEROX CORPORATIONInventors: Edul N. DALAL, Wencheng WU, Lalit Keshav MESTHA
