Abstract
The present disclosure relates to a method, device, storage medium and electronic device for self-annotation of document images, which can realize self-annotation of document images, and the annotation results are reliable. The method includes: obtaining a document image and an original document image corresponding to the document image; performing tilt correction on the document content in the document image to obtain a corrected image; and determining the conversion relationship between the corrected image and the document image; based on the optical flow field between the original document image and the corrected image, and the conversion relationship, performing inverse transformation processing on the document information extracted from the original document image, and annotating the inversely transformed document information on the document image. It does not require a large amount of manpower, and ensures the integrity and clarity of the document image.
