In this video, we are going to learn how to detect text in images. We will learn how to detect individual characters and words and how to place bounding boxes around them. We will also look at how to detect only digits.

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.

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.

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

Hi Murtaza, you see your loop to DISPLAY SOME SAMPLES IMAGES OF ALL THE CLASSES, if the folder names were categorical/strings instead of numerical, i.e. (sign1, sign2, sign3...etc instead of 0,1,2,3..etc) how would you iterate through these folders? would you still use iterrows? Thank you

@SliderBlues 3 года назад

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 3 года назад

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

@kevinalexander4959 3 года назад

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 3 года назад

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

I have a table of prices (with money values), and I have an algorithm in Python to calculate the final value (with the taxes I want for me, and rounded). But I write each value into the software, and then it returns me the value I want, and then I put in a excel table. Is there a way to take the values from the first table, run the algorithm and then return me a csv or xlsx table with the new values? You don't need to do a full search, I just want a way to go to learn (opencv, etc). In Python I just know tkinter, but the bases.
