Abstract: Disclosed is a method of classifying a document for a straight-through processing (STP) using memory enabled modelling. The method includes receiving, performing a content extraction from the input image, and selecting a template with the highest matching probability from a database. The method further includes postprocessing the extracted content based on the predicted template and validating the extracted content. Thereafter, the method includes classifying the document for the STP if the extracted content is successfully validated corresponding to each of the image quality validation, the refined content extraction validation, and the layout validation.
