  • Text classification
    Patent number: 11551461
    Abstract: A text classifying apparatus (100), an optical character recognition unit (1), a text classifying method (S220) and a program are provided for performing the classification of text. A segmentation unit (110) segments an image into a plurality of lines of text (401-412; 451-457; 501-504; 701-705) (S221). A selection unit (120) selects a line of text from the plurality of lines of text (S222-S223). An identification unit (130) identifies a sequence of classes corresponding to the selected line of text (S224). A recording unit (140) records, for the selected line of text, a global class corresponding to a class of the sequence of classes (S225-S226). A classification unit (150) classifies the image according to the global class, based on a confidence level of the global class (S227-S228).

  • System and method for document orientation detection
    Patent number: 8712188
    Abstract: In one embodiment, a method of detecting document orientation includes capturing a document image, binarizing each subimage of the document image to retain textual content and eliminate graphic and noise content from the document image, detecting portrait or landscape orientation based on values computed from strip-based projection profiles, and detecting up or down text orientation based on a text-asymmetry ratio computed from strip-based projection profiles.
