OCR using Python, Tesseract and OpenCV in a Docker container

OCR Tesseract Docker

Allows upload of an image for OCR using Tesseract and deployed using Docker. This uses Flask, a light weight web server framework - but for development purposes only. OpenCV is used to reduce noise in the image for better processing by pytesseract. Uploads on AWS are limited to 2MB - below are 3 images of a job posting taken on a Pixel 2XL phone, and reduced in size using Gimp by adjusting quality.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

You will need Docker installed on your system and a command line editor.

Docker
Git Bash (on Windows)
Terminal (Linux or Mac)

Installing and Running

You can clone this repository or download a zip file, build and run the Docker image.

$ docker build -t ocr-tesseract-docker .
$ docker run -d -p 5000:5000 ocr-tesseract-docker

OR you can pull and/or run the Docker image from my repository on Docker Hub

docker pull ricktorzynski/ocr-tesseract-docker
docker run -d -p 5000:5000 ricktorzynski/ocr-tesseract-docker

Then open up browser to http://localhost:5000

You can use these images to test it - these are photos of a job posting:

• Job Posting 1
• Job Posting 2
• Job Posting 3

Deployed to AWS Elastic Beanstalk
