Invoice-GPT Report
📅 2024 · Tech: openCV, Tesseract, OpenAI API
In this report, I explore the current technologies and tools available
in 2024 that can assist in implementing a basic pipeline for document
data extraction, focusing on invoices and receipts.
Highlights
-
Image processing: We delve into pre-processing
techniques using OpenCV to prepare image files for OCR. This
includes steps such as noise reduction, thresholding, and image
enhancement to improve OCR accuracy.
-
OCR: We utilize the Tesseract API to extract
characters from the processed image files. This section covers the
setup, configuration, and optimization of Tesseract for various
document types.
-
NLP: For extracting meaningful insights from the
text, we leverage the OpenAI GPT API. This involves using natural
language processing to structure and interpret the extracted data,
ensuring high accuracy and reliability.
Outcomes
With minimal tuning and hyperparameter adjustments, the report
demonstrates the ease and potential of achieving production-grade data
extraction from documents. The results illustrate the effectiveness of
combining image processing, OCR, and NLP technologies to create a
robust document data extraction pipeline.
