what on earth was the point of the first 2:20? I though it was going to be an interesting fact that the positioning block was a ratio of the overall dimesions. Nope!
Format information, has a BCH code for error correction. The data bytes block have Reed Solomon codes for error correction. And that is the main math in the QR codes. There is other too.
Sorry I didn't learn any math on how QR codes works. I'm assuming over a billion people could be assigned a code and they would all be different.... looking for that kind of math
I HAVE NEVER ENCOUNTER ANYTHING THAT I COULDNT UNDERSTAND EVEN JUST A VERY LITTLE OF ANYTHING!!! I UNDERSTOOD 21X21. THAT IS IT. I AM EITHER MUCH NOT SMARTER (😊) THAN I FEEL THAT I AM OR THIS VHDEO IS NOT MADE TO EXPLAIN ANYTHING BUT SIMPLY JUST TO RAMBLE AND CONFUSE. THERE IS A VIDEO ABOUT DELTA P THAT IS SUPER FUNNY AND INFORMATIVE. MUCH WATCH
well, sorry to say this, but this video is for nothing.... Doesn't explain use of mask in detail, doesn't say, how it is read. What will happen, if i want to store binaryx data containing only 0, there are now 4 white squares everywhere, how i can know, which of them is ending?
Wow, this was awful, like listening to a high guy explain QR codes, never getting to any point.
I didn’t understand anything you said. I only understood the matrix is 21 x 21.
It’s a great way to start 😊
You forgot the message length indicator (10 bits for version 1) above the encoding indicator.

This is a very nice illustration but it's not the math 😅 but still super cool. Thanks
It's like you're reading notes in point form except you've erased all the headings. What a ramble. I feel sorry for your students.
You ever wonder why everyone says you’re not likable?
@@YerryBalenzuela No, I know why.
@@YerryBalenzuela Probably because he says it like he sees it, in a world of snakes who pretend to be kind.
Please no background music... thank you for the Video!
Thanks for your opinion
Very educative ...easy to understand especially if you know basic maths including binary digits ... thanks a lot.
Muito interessante, professor! Obrigado.
What are you talking about? 😢
Wonderful!! Thanks. How would a whole URL be saved in that small amount of data squares ? Any video on that ? Thanks
Depends of data kind in small right below place
@ 7:37 I believe your final read is incorrect based on the keep/invert rules. (Row 1, Block 5) should be white instead of black.
Thanks for the explantion

For example for example for example for example for example for example this is horrible
Haha... I was wondering about that too and looking in the comment to see if anyone noticed. Honestly, I found the explanation confusing. :(
I think I was mislead by the title of the video 😵💫A lot of info about QR graphics representation but nothing about the math.
the math in this video is that its a 21x21 matrix duhh
thanks professor. :)
You are welcome 😊
Thank you sir
You are welcome 🤗
nice vedio, so educative ❤️❤️
Superb sir. Very well explained.
thanks
Atul bhangi 👌
I understand one thing about QR CODES now😂 you have to understand its a square within a ⬛ square😂😂😂😂😂😂😂
Louder!
Nice presentation
Thanks
Nice animation
Thanks ;)

Professor tem este video em português?
Ainda não, mas farei também
@@ProfessorJulioLombaldo se colocar legendas já está ok
So I finally know it’s 21 by 21
My question is how is that possible?

Ok
Where's the math?
21x21 matrix how could u not see it 🙄
Hello sir I have a problem what is fill in the E1,E2,E3,E4.... blocks plz help me
Too much "for example", why is that example made?
I understand nothing new

just say words, call it a video
Poor explanation very bad english.
