Aspects of the disclosure provide for a method for updating business information. A business at a business location and a reference image for the business at the business location may be selected for an update. From a number of more recent images, a comparison image may be selected based on a likelihood that the comparison image captures the business location. Text and visual features reference image may be compared with text and visual features of the comparison image to determine a text similarity score and a features similarity score. A confidence level indicating whether the business in the reference image is in the comparison image may then be determined using the text similarity score and the feature similarity score. According to the confidence level, the business information of the business may be updated.

A Mixed Media Reality (MMR) system and associated techniques are disclosed. The MMR system provides mechanisms for forming a media document that includes media of at least two types (e.g., printed paper as a first medium and digital content and/or web link as a second medium). The MMR system provides mechanisms for forming a 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 facilitates business methods that take advantage of the combination of a portable electronic device, such as a cellular camera phone, and a paper document.

System and methods for creation and use of a mixed media environment

A Mixed Media Reality (MMR) system and associated techniques are disclosed. The MMR system provides mechanisms for forming a mixed media document that includes media of at least two types (e.g., printed paper as a first medium and digital content and/or web link as a second medium). In one particular embodiment, the MMR system includes a content-based retrieval database configured with an index table to represent two-dimensional geometric relationships between objects extracted from a printed document in a way that allows look-up using a text-based index. A ranked set of document, page and location hypotheses can be computed given data from the index table. The techniques effectively transform features detected in an image patch into textual terms (or other searchable features) that represent both the features themselves and the geometric relationship between them. A storage facility can be used to store additional characteristics about each document image patch.

Data organization and access for mixed media document system

Various aspects can be implemented for determining optical character recognition (OCR) parameters using an OCR engine. In general, one aspect can be a method that includes using an optical character recognition (OCR) engine in a base configuration to generate one or more OCR responses corresponding to one or more sample pages of a document. The method also includes identifying a dominant OCR parameter for the document based on the one or more generated OCR responses. Other implementations of this aspect include corresponding systems, apparatus, and computer program products.

Determining optical character recognition parameters

A Mixed Media Reality (MMR) system and associated techniques are disclosed. The MMR system provides mechanisms for forming a mixed media document that includes media of at least two types (e.g., printed paper as a first medium and digital content and/or web link as a second medium). 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&#xae; 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.

Techniques for annotating or bookmarking digital information. The digital information is annotated based upon events determined from the digital information. The digital information that is annotated may comprise one or more types of information including but not restricted to video information, audio information, images, documents, slides information, whiteboard information, notes information, and the like.

Event-driven annotation techniques

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.

Gesture-based selection text recognition

A Mixed Media Reality (MMR) system and associated techniques are disclosed. The MMR system provides mechanisms for forming a mixed media document that includes media of at least two types (e.g., printed paper as a first medium and digital content and/or web link as a second medium). In one particular embodiment, the MMR system provides for image matching portions of a document.

Method and system for image matching in a mixed media environment

Techniques for encoding a media object are provided. First information is determined from an input media object. Second information is then determined from the input media object. A first visual representation is created based on the first information and a second visual representation is created based on the second information, wherein an output media object is constructed from the first and second visual representations.

Gesture-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.

On-screen guideline-based selective text recognition

A printing system enables the printing of enhanced documents using a semantic classification scheme. A printing system receives an image to be printed. The system classifies the image according to the semantic classification scheme and, based on this classification, performs enhancement processing on the image. Depending on the desired application, the printing system may recognize and classify any number of image types and may then perform various enhancement processing functions on the image, where the type of enhancement processing performed is based on the classification of the image.
