Text Detection with OpenCV in Python | OCR using Tesseract (2020)

[@ishtiaqahmad4118]

By chance I entered last 5 years before in programming languages. You will note my background is Accounting. For now it is sufficient that I am 75 years old man but I am learning Django, Ai, Machine Learning and etc., Last five years I asked my instructor of Java (Note= At that time, I did not know A,B, C of any programming but I know a sufficient knowledge about Programming - I am a lot thankful of Respectable Great Zia Khan) that I can check cross medical bill of the any person, but he could not replay. I am very happy of this watching Video, I can solve this last 5 years dream can be solved by python with AI Insha-Allah. Now I am trying to launch my E - Commerce Website very soon with Python, I shall contact very soon with you for a big project Insha-Allah. Ishtiaq Ahmed Siddiqui KARACHI

For windows , Instead of down manually downloading and installing just do : pip install tesseract

Your tutorials are awesome. I already shared your channel with my students. I visited so many channels for learning opencv and out of that your videos stands out.

[@murtazasworkshop]

I am glad i could be of help. and thanx for sharing

[@aham3687]

Awesome video. I was looking for technology that could read image captcha and extract text in the backend. Then submit text to the server without users requiring to type the captcha and your video solved my issue.

[@choogiesaur]

amazing, would you share your code as an example?!

[@quasa0]

@@choogiesaur did you figure it out?

[@jairajsahgal5062]

23:13 " I have no idea why they did this" made me chuckle.

[@kevinalexander4959]

used this with a webcam to take an image and parse text from (like a piece of paper or menu on a phone), then you can take the .png snapped by the webcam and analyze with image_to_string(), takes about half a second to read text presented and the webcam's settings has to be on point with brightness and all that stuff

[@mehmettatli07]

so we cannot use this one as a real time word detection metod? How many frames did you get when you use with your webcam? i just want to use it for real time detection ,if you answer to me. Thx a lot

[@johntamplin]

Good video. From 20:20 onwards you are using the variable 'x' for both the loop count and the x-dimension of the bounding box. You got lucky that it didn't impact the results of the code.

For macUser : first write at terminal - which tesseract then copy that path and paste it in tesseract cmd path pytesseract.pytesseract.tesseract_cmd = ‘path '

This tutorial is short and sweet. I like it. Currently, i'm having problem in detecting digits only. Instead of detecting digits only, it detects everything. i follow this cong: r'--oem 3 --psm 6 outputbase digits' pycharm community 2020 python-3.8.2

[@amortalbeing]

Thanks a lot. The `image_to_boxes()` returns `x1, height1, x2, height2`. if you renamed them like this it would be much more clear.

[@SliderBlues]

Thanks for the tutorial! It was very helpful for me getting a handle on OCR and Opencv for a redaction project I was working on. Now looking at fictionalizing text in an image. Ideally would like to replace words, like for an address, with different ones using the same font and size for the text. Not finding any solid examples of this that work. Would love to hear your take on how that might be accomplished.

[@murtazasworkshop]

You could do it with opencv python but it you want an end product you might want to look at unity.

Is it possible to get the whole bounding box of a word by combining boxes from every character?

[@petergoodall6258]

My understanding is that ‘text detection’ tells you if you have text or not, rather than giving the value of the text. It’s a simpler process.

[@nicoarasamuel1173]
