PURE ADVERSARIAL APPROACH FOR IDENTIFYING TEXT CONTENT IN IMAGES

摘要

A pure adversarial optical character recognition (OCR) approach in identifying text content in images. An image and a search term are input to a pure adversarial OCR module (920), which searches the image for presence of the search term. The image may be extracted from an email by an email processing engine. The OCR module (920) may split the image into several character-blocks that each has a reasonable probability of containing a character (e.g., an ASCII character). The OCR module (920) may form a sequence of blocks that represent a candidate match to the search term and calculate the similarity of the candidate sequence to the search term. The OCR module (920) may be configured to output whether or not the search term is found in the image and, if applicable, the location of the search term in the image.
