Happy to see the videos on FFT back and running. Another great one!

[@jumbyvt6839]

Took me two videos to subscribe. The quality and content of your material incredible. I really enjoy understanding how the magic happens and you make a hell of a job. Cheers!

I have zero engineering background, but find the entire series super clear and intuitive. Really enjoy this. Thanks!

[@matlabAI]

Genius

This video summed up my 2008 hackathon concept. I had no idea I was inspired by people who had come up with this already or were already talking about it.

[@johanvandermerwe7687]

I like the explanations, keep up the great work!

[@Eigensteve]

Thanks!

[@eofirdavid]

Thanks. As a mathematician who is always looking for interesting applications of mathematics, this was really an interesting demonstration.

[@vincentl7022]

really like this explanations

The last part made me realise why applying a high-pass filter reveals the edges on an image : the edges are the high frequency content because the color changes very quickly in the span of a few pixels.

This video is really awesome but I am wondering if this method if we implement on the 3 color channel to keep the image colored

It needs to be 255 instead of 256. Color ranges from 0-255
Cheers

[@mrseanpaul81]

That is awesome!

[@josephskt8558]

Wonderful!

I really enjoy the discussion of the concepts in its plain, intuitive form. The quality of the video is implacable.

Is FFT or SVD better for compression?

[@manashisarkar9775]

Dr. Brunton, how do you know about (keep track of) all these examples you present, e.g. the toy story example, and other examples throughout the series? Thanks a lot for the content!

[@lalasampritray375]

Thank you.

[@ncclementi]

Is it possible to recover the color image, or to do the analysis on full color? If so how would you go about it? Thanks, great video!

[@greenpumpkin172]

just use FFT for each channel

[@uzivatel123]

thank you so much

[@sepehrsadeghi2386]

it was a good help.

[@ayonmustafi744]

thanks alot sir

[@Aidalwaysmiling013]

where can I find the video's code?

[@user-sm9hj2gj2u]

Where can we find the code for this to download?

[@Kong9901]

very cool :)

[@shirishavissom129]

Can anybody tell me how to import this image please

[@treksis]

the last 3 min is the killer contents where the 3d pixel intensity diagram becomes an actual image.

[@NicolasUnger]

Anyone coming from Veritasium's video?

[@bxch5199]

The interface of showing image in python is way worse than in matlab :D

[@shirishavissom129]

Hey do you know how to do that?

[@shirishavissom129]

Could you please help me with importing this image?

[@shirishavissom129]

I'm stuck there
