  • Method of character recognition in written document
    Patent number: 11151402
    Abstract: A method for recognizing characters in an image of a document having at least one alphanumeric field. The method includes the steps of enhancing an image contrast to highlight the characters in the image; detecting contours of objects in the image to create a mask that highlights the characters; segmenting the image using a tree with connected components and applying the mask thereto in order to extract the characters from the image; performing a character recognition on the extracted objects. A device for implementing the method.
    Type: Grant

  • Character recognition method
    Patent number: 10885326
    Abstract: A method for recognizing characters in an image of a document having at least one alphanumeric field. The method has the steps of: segmenting the image to identify objects therein; defining a bounding box around each object; making multiple successive selections based on different descriptors and dividing the bounding boxes into a plurality of cells for each of which a texture descriptor is determined as a gradient oriented histogram; performing character recognition on the finally selected bounding boxes. A device for implementing the method.
