  • Patent number: 8693779
    Abstract: Methods and systems for segmenting printed media pages into individual articles quickly and efficiently. A printed media based image that may include a variety of columns, headlines, images, and text is input into the system which comprises a block segmenter and an article segmenter system. The block segmenter identifies and produces blocks of textual content from a printed media image while the article segmenter system determines which blocks of textual content belong to one or more articles in the printed media image based on a classifier algorithm. A method for segmenting printed media pages into individual articles is also presented.

  • Publication number: 20140044365
    Abstract: A computer-implemented method of managing information is disclosed. The method can include receiving a message from a mobile device configured to connect to a mobile device network (the message including a digital image taken by the mobile device and including information corresponding to words), determining the words from the digital image information using optical character recognition, indexing the digital image based on the words, and storing the digital image for later retrieval of the digital image based on one or more received search terms.

  • Patent number: 8218913
    Abstract: The present invention relates to systems and methods for identifying front pages from images representing media. In an embodiment, a system for identifying at least one front page within an image representing media is provided. The system includes a matcher, an aggregator and a reviewer. In another embodiment, a method for identifying at least one front page within an image representing media is provided. The method includes comparing each page to matching criteria to produce a matching confidence score. The method also includes aggregating, as front page candidates, each page having a matching confidence score that exceeds a matching confidence score threshold. The method further includes receiving decision information and identifying front pages from front page candidates based upon the decision information. According to another embodiment, the matching criteria may comprise at least one local, affine invariant feature point.

  • Patent number: 7813582
    Abstract: One embodiment of the present invention provides a system that enhances sharpness of object boundaries in an image. During operation, the system first receives an image. Next, the system computes gradients of color values for pixels in the image. The system then computes displacement vectors for pixels in the image, wherein the magnitude of the displacement vector for a given pixel is proportional to the magnitude of the gradient of the color value at the given pixel. The system next replaces the color values for the pixels, wherein the color value for a given pixel is replaced with a color value obtained from a location at the end of the displacement vector for the given pixel.
