Methods, systems, articles of manufacture, and apparatus for decoding purchase data using an image

An apparatus comprising:

• interface circuitry to obtain an image of a purchase document having a first region and a second region;
• machine readable instructions;
• and
• at least one processor circuit to be programmed by the machine readable instructions to:
• execute a first artificial intelligence (AI) classifier model based on the first region to generate a first mask, the first AI classifier model to classify first pixels of the first region as belonging to a text line, the first mask to identify the first pixels;
• generate first bounding boxes on the image based on the first mask, the first bounding boxes corresponding to rows of the purchase document;
• execute a second AI classifier model based on the second region to generate a second mask, the second AI classifier model to classify second pixels of the second region as belonging to a column, the second mask to identify the second pixels;
• generate second bounding boxes on the image based on the second mask, the second bounding boxes corresponding to columns of the purchase document;
• generate a data frame to represent a structure of the purchase document based on (a) text regions extracted from the image, (b) the first bounding boxes, and (c) the second bounding boxes;
• and
• extract purchase information from the data frame.
