In one particular embodiment, the MMR system includes an MMR user, a MMR computer, a user printer that produces a printed document, a networked media server, an office portal, a service provider server, an electronic display that is electrically connected to a set-top box, a document scanner, a network, a capture device, a cellular infrastructure, wireless fidelity (Wi-Fi) technology, Bluetooth® technology, infrared (IR) technology, wired technology, and a geo location mechanism. The MMR system of the present invention provides mechanisms for forming a mixed media document that includes media of at least two types, such as printed paper as a first medium and a digital photograph, digital movie, digital audio file, or web link as a second medium. Furthermore, the MMR system of the present invention facilitates business methods that take advantage of the combination of a portable electronic device, such as a cellular camera phone, and a paper document. | 07-01-2010 |
20110081083 | GESTURE-BASED SELECTIVE TEXT RECOGNITION - An image is displayed on a touch screen. A user's underline gesture on the displayed image is detected. The area of the image touched by the underline gesture and a surrounding region approximate to the touched area are identified. Skew for text in the surrounding region is determined and compensated. A text region including the text is identified in the surrounding region and cropped from the image. The cropped image is transmitted to an optical character recognition (OCR) engine, which processes the cropped image and returns OCR'ed text. The OCR'ed text is outputted. | 04-07-2011 |
20110123115 | On-Screen Guideline-Based Selective Text Recognition - A live video stream captured by an on-device camera is displayed on a screen with an overlaid guideline. Video frames of the live video stream are analyzed for a video frame with acceptable quality. A text region is identified in the video frame approximate to the on-screen guideline and cropped from the video frame. The cropped image is transmitted to an optical character recognition (OCR) engine, which processes the cropped image and generates text in an editable symbolic form (the OCR'ed text). A confidence score is determined for the OCR'ed text and compared with a threshold value. If the confidence score exceeds the threshold value, the OCR'ed text is outputted. | 05-26-2011 |
20110128288 | Region of Interest Selector for Visual Queries - A client system receives an image such as a photograph, a screen shot, a scanned image, or a video frame. The image has a first resolution which is likely larger than a maximum resolution for visual queries. As such, if a visual query were created from the image some resolution would be lost. Instead, a user selects a region of interest within the image. The region of interest has a second resolution, which is smaller than the first resolution. The client system then creates a visual query from the region of interest. The visual query has a resolution no larger than a pre-defined maximum resolution for visual queries. Because the visual query is created from the region of interest rather, than the entire received image, most of the resolution is concentrated specifically on the region of interest. The visual query is then sent to a server system. | 06-02-2011 |

The process proceeds by locking the data set in the file system such that no direct access of the data set is allowed. Read and/or write requests for the data set are processed using the representation of the data set in the designated server address space. The data set in the file system is updated with any changes made to the representation of the data set in the designated server address space. | 09-25-2014 |
