1. A method for stamp detection and classification, comprising:

receiving, by a computing device, textual data of a document and image data comprising a capture of the document;

identifying, by the computing device, a presence of a stamp on the document based on a plurality of intermediate detections of the stamp from the textual data and image data by a corresponding plurality of machine learning models;

responsive to identifying the presence of the stamp, extracting, by the computing device, a subset of the image data comprising the stamp;

extracting, by the computing device via optical character recognition, text from the subset of the image data; and

storing, by the computing device in a database, the subset of the image data comprising the stamp, the extracted text from the subset of the image data, and an identification of a classification of the stamp.
