Patent number: 9256795Abstract: Various embodiments enable the identification of semi-structured text entities in an imager. The identification of the text entities is a relatively simple problem when the text is stored in a computer and free of errors, but much more challenging if the source is the output of an optical character recognition (OCR) engine from a natural scene image. Accordingly, output from an OCR engine is analyzed to isolate a character string indicative of a text entity. Each character of the string is then assigned to a character class to produce a character class string and the text entity of the string is identified based in part on a pattern of the character class string.Type: GrantFiled: March 15, 2013Date of Patent: February 9, 2016Assignee: A9.com, Inc.Inventors: Douglas Ryan Gray, Xiaofan Lin, Arnab Sanat Kumar Dhua, Yu Lou

Publication number: 20160028945Abstract: Various approaches provide for detecting and recognizing text to enable a user to perform various functions or tasks. For example, a user could point a camera at an object with text, in order to capture an image of that object. The camera can be integrated with a portable computing device that is capable of taking the image and processing the image (or providing the image for processing) to recognize, identify, and/or isolate the text in order to send the image of the object as well as recognized text to an application, function, or system, such as an electronic marketplace.Type: ApplicationFiled: October 2, 2015Publication date: January 28, 2016Inventors: ADAM WIGGEN KRAFT, KATHY WING LAM MA, XIAOFAN LIN, ARNAB SANAT KUMAR DHUA, YU LOU

Publication number: 20160005189Abstract: Approaches are described for rendering augmented reality overlays on an interface displaying the active field of view of a camera. The interface can display to a user an image or video, for example, and the overlay can be rendered over, near, or otherwise positioned with respect to any text or other such elements represented in the image. The overlay can have associated therewith at least one function or information, and when an input associated with the overlay is selected, the function can be performed (or caused to be performed) by the portable computing device.Type: ApplicationFiled: September 10, 2015Publication date: January 7, 2016Inventors: Douglas R.

Publication number: 20150339536Abstract: Various embodiments provide methods and systems for identifying text in an image by applying suitable text detection parameters in text detection. The suitable text detection parameters can be determined based on parameter metric feedback from one or more text identification subtasks, such as text detection, text recognition, preprocessing, character set mapping, pattern matching and validation. In some embodiments, the image can be defined into one or more image regions by performing glyph detection on the image. Text detection parameters applying to each of the one or more image regions can be adjusted based on measured one or more parameter metrics in the respective image region.Type: ApplicationFiled: August 3, 2015Publication date: November 26, 2015Inventors: Xiaofan LIN, Adam Wiggen KRAFT, Yu LOU, Douglas Ryan GRAY, Colin Jon TAYLOR

Patent number: 9165406Abstract: Approaches are described for rendering augmented reality overlays on an interface displaying the active field of view of a camera. The interface can display to a user an image or video, for example, and the overlay can be rendered over, near, or otherwise positioned with respect to any text or other such elements represented in the image. The overlay can have associated therewith at least one function or information, and when an input associated with the overlay is selected, the function can be performed (or caused to be performed) by the portable computing device.Type: GrantFiled: September 21, 2012Date of Patent: October 20, 2015Assignee: A9.com, Inc.Inventors: Douglas R.

Publication number: 20150254507Abstract: Various embodiments enable a device to perform tasks such as processing an image to recognize and locate text in the image, and providing the recognized text an application executing on the device for performing a function (e.g., calling a number, opening an internet browser, etc.) associated with the recognized text. In at least one embodiment, processing the image includes substantially simultaneously or concurrently processing the image with at least two recognition engines, such as at least two optical character recognition (OCR) engines, running in a multithreaded mode. In at least one embodiment, the recognition engines can be tuned so that their respective processing speeds are roughly the same. Utilizing multiple recognition engines enables processing latency to be close to that of using only one recognition engine.Type: ApplicationFiled: May 26, 2015Publication date: September 10, 2015Inventors: Xiaofan Lin, Arnab Sanat Kumar Dhua, Douglas Ryan Gray, Yu Lou
