    Abstract: Methods and apparatus to measure brand exposure in media streams are disclosed. Example apparatus disclosed herein are to determine a first histogram based on at least one of luminance components or chrominance components of a first frame of video, and determine a second histogram based on at least one of luminance components or chrominance components of a second frame of the video. Disclosed example apparatus are also to detect a transition in the video based on the first histogram and the second histogram, and responsive to the detection of the transition in the video. Disclosed example apparatus are further to process a region of interest within at least one of the first frame or the second frame to detect a logo in the region of interest.

    Abstract: Methods, storage systems and computer program products implement embodiments of the present invention for protecting a computing device. These embodiments include detecting that an email is received by the computing device, the email including a Uniform Resource Locator (URL) for a web page in a first domain. The web page is retrieved from the domain, and a set of keywords are extracted from the retrieved web page. A query included the set of keywords is submitted to a search engine, and a response to the query is received from the search engine, the response indicating a set of second domain. Finally, in response to detecting that the first domain does not match any of the second domains, an alert for a phishing attack is generated.

    Abstract: A method and a computer system for preflighting a graphics artwork file. The method includes storing rules corresponding to an object, a set of recognition inputs for identifying the object, and a graphics artwork file to be preflighted. An image is rendered from the graphics artwork file and machine vision identifies a representation of the object in the rendered image, a characteristic of the object, and a value for the characteristic. The identified characteristic value is checked against corresponding values embodied in the rules, and an output of the checking step is provided. The system comprises at least one computer processor, an input, an output, and a plurality of computer memory modules for storing the rules, the recognition inputs, the artwork file, and instructions for performing the rendering, the machine vision, and the checking method.

    Abstract: Techniques for providing improved optical character recognition (OCR) for receipts are discussed herein. Some embodiments may provide for a system including one or more servers configured to perform receipt image cleanup, logo identification, and text extraction. The image cleanup may include transforming image data of the receipt by using image parameters values that optimize the logo identification, and performing logo identification using a comparison of the image data with training logos associated with merchants. When a merchant is identified, a second image clean up may be performed by using image parameter values optimized for text extraction. A receipt structure may be used to categorize the extracted text. Improved OCR accuracy is also achieved by applying on format rules of the receipt structure to the extracted text.
