Hi there! I wanted to thank you for the incredible video on text detection in images using `pytesseract`, `easyocr`, and `keras_ocr`. It was exactly what I needed to resolve all my doubts about which tool to use in my projects. Your clear explanation and comparative analysis helped me understand the advantages and disadvantages of each, allowing me to make an informed decision. Thanks again for sharing your knowledge and for the quality of your content. I would love to see more videos like this, where you explain and compare different tools and technologies. Keep up the excellent work! Best regards and well done! Philippe

I had fun watching this video! Great job. Also very nice to see you making typos and then fixing it. Many people on KZread cut those parts and it gives some sort of weird feeling like the person is pretending like they never make mistakes. It's impossible!

Great video! Clear and concise. You've earned my subscription.

Thanks for showing how to use all three methods. For the comparison part I think you could go a lot more in depth on the results. For most applications the results seem largely insufficient to me, but for some applications it is already fine.

Highly appreciated

Hello Rob. Can you please tell what you think about which one of these 3 will work best if I have to extract text from images of products of inventory? for example soft drinks pictures, chips, snacks, chocolates, tissue boxes, vanity products, etc.

For document files, how do easy ocr and keras ocr perform as compared to Tesseract?

Hey Rob, thanks a ton for the awesome job you do, I have learnt a lot of new cool stuff (I was only aware of pytessaract, thought it is the best one and tried it on pictures), now I will definitely give a try to the other libraries as well. As I already mentioned, overall you are doing an extremely great job, I just have 1 idea and 1 suggestion : ) 1) idea: as you mentioned in the video, we have the annotations (like the ground truth) already provided in the dataset, right? Wouldn't it be a good idea to check the results vs the ground truth? I.e. smth like lib2 has 3 out of 10 annotations correctly ( recall 0,3) out of 6 predicted texts (0,5 precision) smth like accuracy etc. I understand, this is not perfect as it could only partially extract the text (like miss 1-2 letters) or recognize letter 'G' instead of 'C'. I mean the question is: what's a fair way to have some numerical result based on the dataset? Say library 1 has accuracy X precision Y and recall Z and based on this values and the confusion matrix to be able to make a selection of a library given a particular dataset? 2) Suggestion: I am mentioning this 3rd time already, but your videos are just marvellous, I mean extremely informative, to the point, no second wasted at all. Just perfect. So, what I would really love to see is (as you asked about suggestion for some next video) is almost the same kind of video for some audio task. There is this new BLOOM model out today, I haven't checked it yet, but maybe you could pick some models (like based on wav2vec2) that recognize voice (asr) and compare them using transformers and huggingface for example? Would really be nice to see some comparison of different models in some audio related task, where the whole pipeline (like loading audio, extracting the numerical features, feeding to some pretrained model and finally prediction) would be implemented and validated based on say word error rate. Thanks in advance ; )

Great comment. Wow! Lots to respond to. For #1 that’s a great idea and I had considering doing a more formal evaluation metric to compare the models but ended up deciding it would be too much for this video. I think most of these models are released with their metrics on similar datasets. For #2 I’ll have to check out the model you are referring to I’ve never heard of it before but will read up. I was considering making a video on the new language translation model that meta released last week. Thanks for watching and I appreciate the feedback!

Hi Rob, a very informative video thank you! After we extract the data what is the best solution to save it into a table without missing the context of future images or PDFs? Per example if I save Customer's First Name from first file, it should be easier to detect it in the next file and save it under the same column

great video! i was asking myself if as a languages i could set "math". i'm trying to get a prediction of number and text together could i use one of this libraries or for handwritten numbers i have to use a totally different library?

Great video, thanks. Which one do you like the best for invoices and business documents. any for handwriting

Nice tutorial! I only try pytesseract in the past with PDF files. For future video recommendation I will like to see something about how you organize your ML experiments. In the competitions do you use some tool in order to try multiple models and hyperparameter tuning?

Yes, I think pytesseract is really good for documents, but not so much for extracting text from images. Great reccomendation for future videos.
