Abstract
A method for recognizing text in graphical drawings includes creating a binarized representation of a drawing to form an electronic image of pixels. The image is discriminated between text regions and lines in the image by grouping pixels into blocks and comparing blocks with a predetermined format to identify text regions. The lines that remain in the text regions are removed to create text only regions. The text is recognized in the text only regions.
