Build a Custom OCR Model in TensorFlow: A Step-by-Step Tutorial

In this tutorial, we will explore how to recognize text from images using TensorFlow and the CTC loss function in a neural network model. We will start with an introduction to text recognition and the different approaches used to extract text from images. We will then dive into the specifics of using TensorFlow and the CTC loss function to build our custom OCR system. The tutorial will also introduce a new open-source library called MLTU (Machine Learning Training Utilities) that can be used to store code for future projects. By the end of this tutorial, you will have a working OCR model that you can use to recognize text from images. This is the first part of a tutorial series, so stay tuned for more in-depth content on text recognition and other machine-learning topics.

I have a project assignment. I am making a mobile application that will convert Braille to plain text. I will do the mobile part with Flutter. I don't know much about model training. Do you have any advice? How can I do this in the most correct way?

Hello, I have a quick question. I’m using a custom dataset. What’s the most ideal dataset size? My CER stays at 1.00. Is it because my dataset is too small?

hi sir, just a primary question, what pre-knowledge do i need to fully understand the tutroial and the other ones?

[AbduqayumRasulmuhamedov]

Hi I have a question. You trained your model with annotation_train.txt and annotation_test.txt. I am curious about what kind of things you wrote in those files. Because i am also trying to create my custom model. Thanks for your response in advance

Where can i find the dataset and the image folder?

[hamzaomari]

which architecture is this model based on ?
Can you provide me a way for researching more in the state of the art of OCR especially for digital character recognition.

[midhauxgaming]

Hi can I ask for your Dataset I really want to try to train the model again. Thank you!

[bouchrasaidi]

Is there any tutorial u recomand for text detection please ?

[astronaut]

Hi Thanks for video. While I watching this, I saw that the WER is 1.000. what does it mean? why does the WER doesn't goes down?

[maggiezhang]

Thanks for the tutorial. Curious if there is a good tutorial on Text Detection you recommend?

Hi, hello. I want to say that this tutorial is amazing!! Thank you very much.

On an M1 Max GPU training has been running for 3+ hours on first epoch still...I think maybe I've done something wrong but don't want to end the script at this point. I added many custom examples of alphanumeric sequences. I feel like the M1 Max should be able to handle a batch size of 1024. Do you think this sounds like a lower batch size is needed?

This was a great video! I’m trying to get an OCR model to work with Hebrew handwriting, what’s my best options for gathering a training set?

Hey there I really like your videos but I got error at the beginning of the video, JUST when I start the package is not installed to my VS code please can I get help?

[codewithme]

Hi, Thanks for all your Videos .Those Videos helped me a lot
you deserve more subs and views on your channel
Thanks Again

First of all, well done for this video. It is very interesting. I just wanted to ask you a question. Is this possible to use this in a video instead of images? I am trying to train a model that reads number plates. However, number plates vary from a country to another and I am trying to train a model with my country numberplates format.

[primalvision]

Hi thank you for posting ocr videos. can you please tell what is inference speed of the model while using CPU?

[alexrobles]

what can I do if i'm getting the next error in training?: Failed to find data adapter that can handle input: <class 'mltu.dataProvider.DataProvider'>, <class 'NoneType'>

may i use this for business card extraction

[pranay]

where can i get your complete notebook for the reference
