This repository contains a paper collection of the methods for document image processing, including appearance enhancement, deshadow, dewarping, deblur, and binarization.

A Gated and Bifurcated Stacked U-Net Module for Document Image Dewarping

Sheet music dewarping, primarily for pictures taken with smartphones.

A function that takes as input a cropped text line image, and outputs the dewarped image.

Inference, training and evaluation code for our models from the paper "Inv3D: a high-resolution 3D invoice dataset for template-guided single-image document unwarping" (ICDAR) 2023.

Text page dewarping using a "cubic sheet" model

The official code for “DocTr: Document Image Transformer for Geometric Unwarping and Illumination Correction”, ACM MM, Oral Paper, 2021.
