  • Detecting document objects
    Patent number: 10997407
    Abstract: Example implementations relate to detecting document objects. For example, detecting document objects may include a system comprising a pre-processing engine to establish a threshold for a document, wherein a structure of the document is unknown, a detection engine to detect a candidate area in the document, using a Hough transform and connected component analysis to merge detected candidate areas in the Hough transform to a same document object in the document, and a classification module to classify the candidate area as a document object or not a document object.
    Type: Grant

    Assignee: Hewlett-Packard Development Company, L.P.
    Inventors: Perry Lea, Eli Saber, Osborn De Lima, David C. Day, Peter Bauer, Mark Shaw, Roger S. Twede, Shruty Janakiraman
  • Compressing each object in an electronic document
    Patent number: 10594890
    Abstract: A device includes a processor and associated memory; and a compressor for compressing data representing an electronic document, the electronic document comprising a number of objects. The compressor is to determine for each object of the document whether data of that object is to be compressed with lossy or lossless compression and to compress the data accordingly to generate a compressed electronic document.
