OpenCV Python Tutorial #6 - Corner Detection

[@LyingParachute]

Hey Tim. After watching your several videos I noticed, that you struggle breathing while you talk. My girlfriend is a speech therapist and she said that going to this kind of specialist would make your life easier. You should consider implementing simple breathing exercises to prevent larynx disease. It's important, becouse you talk a lot. Thanks a lot for making courses and tutorials, they're great! :)

[@Joker4funify]

Hi Tim! It's great that you continue this series. Please continue it, don't ditch it:) P.S: I'm studying CV at my uni and your tutorials are just gold! Please, continue them. You are amazing, I'm watching you since 2019.

[@breathemath4757]

Just in case you're not a fan of the map function, try: color = [int(x) for x in np.random.randint(0, 255, size=3)]

[@cjay9615]

Don't stop making these videos, some of the best python tutorials on the whole of youtube!!!

[@mrphatmanzach]

Instead of the map(lambda... for the np.random.randint you can also tuple a comprehension for the function. color = tuple(int(x) for x in np.random.randint()) Great video, love your channel!

[@daymaker_trading]

Thank you Tim. You're so good as a teacher. Everything is clear and so fun to learn. Best wishes!

[@faizalimuhammadzoda4731]

This is absolutely amazing. Greetings from Asia.

[@vanchhitdubey]

Just wanted to tell you: you are amazing.

[@peaceandlovetoyou]

If you get errors Corners = np.int0(corners)change np.int0 to np.int_(corners)

[@pythonSefer]

Hi Tim I just wanted to suggest a video idea for you: Make a tutorial about the vim text editor

[@greenmug6436]

just type vimtutor in the terminal

[@davidjack5876]

just wanted to leave this here: "good features to track" was the name of the paper publishing this improved corner detection method

[@youhadayoub9567]

Thank you a lot, I m really injoying your lessons , thank u for the simplicity.

[@Pottavinay-w7f]

@techwithtim the python documentation in the description is not working are there any other websites for that?

[@29namankumar29]

Great video Tim👌✌️

[@cagndurmus2387]

when ı enter the link which is called Relevant Documentation , it says that the page is abondoned . Do you have have a new link of it?

[@bongvatana6803]

Love this tutorial

[@user-ih4ho1wh5h]

I am a little confused with the line 19 at 19:59. Why did you use lambda x: int(x) instead of just a regular int(x). I don't use lambdas a lot so I'm wondering if I'm missing something here.

[@TechWithTim]

Oh good point! I could have actually just passed “int” as the function

[@JM_Tushe]

That's pretty cool, thank you!

[@syedazzamzafar596]

@Tech With Tim The top right corner is left out. there is no line going or emerging from that corner.

[@MrHellmeowmix]

The link to the documentation is "abandonded", do you know where I could find that information? I've tried a few google searches but I don't think I'm finding the right ones

[@jollokim1948]

looking forward to the next video 😏

[@standingpad]

Will there be a image denoiser tutorial?

[@priyangshu7767]

Love your work

I've just watched the 7th part and now 6th is the latest. Accidentally published?

[@TechWithTim]

yep lol

[@aayushpaswan6826]

[@georgegu3374]

on video cam, always set a fixed white-balance like 5500k. otherwise the color on captured image is changing with ambiant light. if you with greyscale, it doesn't matter

[@sitpainghtun5367]

Could you explain me a little more about second for loop ( for j in range(i+1), corners) )

[@tusharikajoshi8410]

it's for all the remaining corners. like, suppose i gives the 1st corner, so j will allow hold the value of all the other remaining corners, one by one, so that we can draw line from the 1st corner to every other corner. I am bad at explaining but I hope it helps.

[@unbox3346]

I was feeling first before refreshing page

[@numo6144]

you can simply write corners = list(map(np.ravel, corners))

[@numo6144]

and also rc = tuple(map(int, np.random.randint(0, 255, size=3)))

[@NoahPeeters]

Could you make a video on image alignment using openCV?

[@manas1743]

Can someone again link the documentation. The link in the description says that the project is moved. Even the name of documentation would be enough for a google search.

Good job man

[@prathamhebbar5800]

Hey Tim. I've known you and been following your tutorials for a while, now. I definitely appreciate your videos and content, don't get me wrong. I don't know why but I've noticed that (in your videos) that there is a sheer lack of expression and enthusiasm in your voice. I would suggest adding expression and enthusiasm in your voice in order to keep the viewers engaged. Best, Pratham Hebbar

[@fionanathanson6580]

Nice video 👍

The complexity of the second half of this video is making me swear under my breath. I've met my intellectual limit, I am legitimately too stupid to understand the part where you put lines between each corner.

Geez, you are very good are making really unreadable code 😅. There are SO many better ways to do some of the logic you show here.
