Abstract
According to one embodiment, a method for detecting, extracting information from, and classifying tables within an original image includes: pre-processing the original image to generate processed image data; detecting one or more tables within the processed image data; extracting the one or more tables from the processed image data; and classifying either: the one or more extracted tables; portions of the one or more extracted tables; or a combination thereof. Additional techniques for pre-processing image data to facilitate detection, extraction of information from, and classification of tables (or portions thereof) are also featured. Corresponding systems and computer program products are included in the scope of the invention. The inventive concepts are also applicable to tabular data arrangements that may not fit a strict definition of a “table.”
