MC-OCR Challenge 2021: Simple approach for receipt information extraction and quality evaluation

Abstract

This challenge organized at the RIVF conference 2021 [12], with two tasks including (1) image quality assessment (IQA) of the captured receipt, and (2) key information extraction (KIE) of required fields, our team came up with a solution based on extracting image patches for task 1 and Yolov5 + VietOCR for task 2. Our solution achieved 0.149 of the RMSE score for task 1 (rank 7) and 0.219 of the CER score for task 2 (rank 1). Our code is available at https://github.com/cuongngm/RIVF2021.
