An example method of extracting structured information from document images comprises: receiving a document image; detecting a tabular structure within the document image; identifying a plurality of rows of the tabular structure, wherein each row of the plurality of rows comprises one or more lines; for each row of the plurality of rows, identifying a set of field types of one or more fields comprised by each line of the one or more lines comprised by the respective row; detecting, in each line of the one or more lines, a set of fields corresponding to a respective set of field types; and extracting information from the set of fields.

Extracting structured information from document images

Systems and methods are disclosed to receive a training data set comprising a plurality of document images, wherein each document image of the plurality of document images is associated with respective metadata identifying a document field containing a variable text; generate, by processing the plurality of document images, a first heat map represented by a data structure comprising a plurality of heat map elements corresponding to a plurality of document image pixels, wherein each heat map element stores a counter of a number of document images in which the document field contains a document image pixel associated with the heat map element; receive an input document image; and identify, within the input document image, a candidate region comprising the document field, wherein the candidate region comprises a plurality of input document image pixels corresponding to heat map elements satisfying a threshold condition.
