OCR API

---

This repository is API based Optical Character Recognition.

Really Simple :)

Just run the server and request to the server with any image file which contains characters. That's all :)

Okay what is the workflow?

• You should install packages. (descripted inside of requirements.txt)
• Run the server for the requests
• Request to the server with the image
• Get your response and Enjoy :)

How can you install packages?

NOTE: Sometimes tesseract might be mischievous. If you are not own the tesseract you can run command below.

$ sudo apt install tesseract-ocr

Then control your tesseract version with this:

$ tesseract --version

After these steps everything will be the simplest. Just run command below.

$ cd ocr_api/
$ pip3 install -r requirements.txt

You have installed those packeges, what you will do next?

Now you can run your server first.

$ uvicorn ocr:app --reload

Then you should be get the messages below:

INFO:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
INFO:     Started reloader process [33226] using statreload
INFO:     Started server process [33228]
INFO:     Waiting for application startup.
INFO:     Application startup complete.

Let's try the server

For testing the server you can use test.png.

$ python3 main.py test.png

What is your response? Absolutely right!

Finally output:
