How Circle Hough Transform works

[@smoothoctopus]

the animation in this and the previous videos are what makes the explanation gold. Finally seeing how the algorithm is applied live really ingrains the idea. nice work!

[@McZockerbock3301]

i love how you showed visually how the algorithm works! that helped so much - great work, thanks

That accumulator animation ist so good. Thank you!

[@GG64du02]

I was looking for something similar to the image you processed as an example but this might be not the solution but it gave me a simpler idea

[@joerakhimov]

This is the best tutorial that I watched in my lifetime! Amazing!

[@parthpatel8532]

Thank you very much. I will 99% have this problem in a Augmented Reality job interview tomorrow, and your video helps me understand the question so much. Hopefully I get the job

[@tkorting]

Good luck. I hope you get the job, and subscribe to my channel as well. Regards

Thanks a lot! This animation is really helpful for learning how the algorithm works.

Thank You!

[@CallMeSwal]

Animation does great job of explaining concept, thanks boss!

[@abarrachina]

The elliptic algorithm would be nice as well

[@carlosgironda1347]

Thank you Thales, this is a very beautiful explanation.

[@AbelBlog]

Great tutorial. Saved me lots of reading time.

[@hoanglong4911]

wow the visualization is so damn cool. thank you!

Well explained. Thanks from India :)

[@mathisart]

What a brilliant tutorial.

[@algolancer]

Notes that mathimatically we can find the center and R of a circle from 3 points of its circumference. I am working in this edia(seems need less time)

[@abbadullahhsaleh2679]

Thanks

[@s04Ker]

Do u have any references method for detecting circle?

[@adrianorcampos]

Bem legal o vídeo, professor! Mt obrigado!!!

Sir, what will happen when we don't know the circle's radius? , since the memory, and computation steps, everything will be so high, right? then how do they do it?

[@madhurabhalerao7894]

Thanks for making the concept easier. Can this algorithm be directly used to detect circles/ wells on a satellite image?

[@tkorting]

Thanks for the feedback, please subscribe to my channel
Yes (and no as well). We have been trying to make this, but sometimes the neighborhood of the circles (and also the interior) provide interference to the circles, and the detection is not accurate.

Hello, nive video and thanks a lot. How can I add speed limit signs detection when a circle is detected? thanks in advance

[@omnificatorg4426]

Can it be solved in a more elegant way? I think we actually don't need to draw a whole circle for every point of the edge, and we don't even need an edge detection filter. Instead of that, we may differentiate the input image to get an array of gradient vectors and fill the accumulator with points according to the vectors' directions (or small arcs, since their angles may be somewhat inaccurate).

[@joskejoske5]

Getting the gradient vectors and edge detection are more or less the same thing. But yes, you can just let the Hough transform 'vote' in the direction of the gradient vectors and the center will light up as well if you choose the correct radius. (no need to draw the whole circle as you said)

[@breakdancerQ]

Damn good, even for a noob like me

[@kranthikumar4674]

hello sir, it was an amazing video thankz for posting. Sir in case if don't know the specified radius can circular hough transform work and explain this with a video and also explain daugman's rubber sheet model normalization process.

[@tkorting]

Thanks for the question, please subscribe to my channel
Some implementations for this perform several hough transforms with different radius, in this case creating not only circles, but cones.
