  • Patent number: 9483834
    Abstract: Object boundary detection techniques are described. In implementations, edges of an object displayed in an image are detected. The image is used to generate a gradient image and a monochrome image. Directional filters are applied to the monochrome image to generate directionally filtered images, which are then applied the gradient image to identify potential boundary lines of the object displayed in the image. A selection can then be made from the potential boundary lines, based on a score associated with each respective potential boundary line, to select lines to represent the boundaries of the object. The selected lines can be used to segment the image into a plurality of segments, and then, using the average color of each segment, one or more of the selected lines can be invalidated as being a false boundary.

  • Patent number: 9235758
    Abstract: Techniques for comparing documents may be provided. For example, a comparison between layouts of the documents may be performed. The comparison may include segmenting the documents into blocks, where an arrangement of blocks of a document represents a layout of the document. Once segmented, similarity metrics, such as distances, between blocks of one document and blocks of the other document may be computed. The similarity metrics may be used to match the blocks between the documents. Further, the similarity metrics between the matched blocks may be added to determine an overall similarity metric between the documents. This overall similarity metric may indicate how similar the documents may be.

  • Patent number: 9223756
    Abstract: A computer implemented method and apparatus for identifying logical blocks of text in a document where document structure information is absent. The method comprises accessing a document, wherein the document comprises a plurality of words; identifying word information for each word in the plurality of words; creating a plurality of text lines based on the word information, wherein each text line in the plurality of text lines comprises one or more words in the plurality of words; and creating a plurality of text blocks derived from the plurality of text lines.

  • Patent number: 9117116
    Abstract: A computer implemented method and apparatus for managing deadline content in a document. The method comprises extracting deadline content from a document; comparing the extracted deadline content to content in one or more existing deadline profiles; and providing for storage on a cloud server, at least one of the extracted deadline content when the extracted deadline content matches the content in an existing deadline profile, or the extracted deadline content and a new deadline profile for the document when the extracted deadline content does not match an existing deadline profile.

  • Patent number: 8457426
    Abstract: A method and apparatus for providing document compression. In some embodiments, the method includes converting a document into a grayscale image, for each gradient component of the grayscale image, creating a monochrome image region, determining pixel variation information for the monochrome image region, and selecting the monochrome image region for a binary mask if the pixel variation information satisfies dynamic threshold data and creating a compressed document using the binary mask.
