The metadata extraction machine transmits a communication to a device of a user based on the identifying of the attribute descriptor corresponding to the attribute of the item depicted in the image. | 04-21-2016 |
20160140398 | CONTEXTUAL INFORMATION OF VISUAL MEDIA - An analysis master control can be configured to derive contextual information of visual media that includes extracted information and extrapolated information. The analysis master control can receive the extracted information characterizing visual media from a recognizer. An information finder can be configured to query a plurality of information sources for information based on the extracted information. The analysis master control can also be configured to match information received from the information sources with the extracted information to form the extrapolated information that characterizes the visual media. | 05-19-2016 |
20160140410 | IMAGE ACQUISITION USING A LEVEL-INDICATION ICON - During an information-extraction technique, visual suitability indicators may be displayed to a user of the electronic device to assist the user in acquiring an image of a document that is suitable for subsequent extraction of textual information. For example, an imaging application executed by the electronic device may display, in a window associated with the imaging application, a visual suitability indicator of a tilt orientation of the electronic device relative to a plane of the document. When the tilt orientation falls within a predefined range, the electronic device may modify the visual suitability indicators to provide visual feedback to the user. Then, the electronic device may acquire the image of the document using an imaging device, which is integrated into the electronic device. Next, the electronic device may extract the textual information from the image of the document using optical character recognition. | 05-19-2016 |
