Saisiko taustamusan voimakkuutta hieman pienemmälle suhteessa puheeseen? Olisi herkästi häiriintyvälle katsojalle helpompi seurattava. Kiitos!

so after that, you use the sinogram to create the image, right?

Ei noin. Ote kirveestä on väärin ja siksi se toimii huonosti.

Väärä tekniikka.

Voxels? Prefilled with elimination?

Do you have any Raw data? and where could I download the data?

you are the best you really helped my thank you so much wish you succes in your life

Oletetaan, että digikamera ottaa kuvan ja se on vääristymätön. Siis havainto on 100 % totta, niin eikö neliöjuuren ottaminen kuvasta vääristä sitä? Ja kuitenkin ihmiset näkevät kuvan parempana. Jään pohdiskelemaan vääristyneen todellisuuden ja kuvan hyvyyden problematiikkaa. Itse aisassa ihan mielenkiintoinen pohdinta-aihe. Ja tästä vielä sivujuonne pohdintoihin: vääristääkö digikamera todellisuutta?

Hi Prof. Siltanen, thank you very much for this amazing video. I plan to follow all the courses and now I am at the begining. I have a question regarding computing tsvd. Dp_alpha(iii,iii) = 1/svals(iii); Why is it not like this Dp_alpha(iii,iii) = svals(iii); ?

That is so cool

Where can I get this please?

<- Problem of understanding the message of this video.

Your work is interesting but I want to apply this model on environmental factors. Could you please guide me?

I would love to see a link to the Matlab code in the description!

I had to watch more than once to work out what was going on. Not sure why it was recommended, but glad it was

Like from Brazil!

Absolutely amazing video!

Bad choice

Thanks, very useful

Thank you for posting this. I have spent weeks finding these codes for my assignment all over the internet. I would not have figured it out without this video as there is no advice from my tuitors that could help.

I really hate the whiteboard sound but it is a great lecture.

it looks too good, can you also elaborate how do you constructed images by these values?

Thanks for the video. Clearly this method works in matlab but I was wondering if directly changing fft coefficients in this manner produces ripples in the time domain signal representation due to the rectangular window effect? Or does matlab handle the maths for youin this regard?

hello sir how can we use this filtered back projection to create 3D image. i have 12 images in 12 direction like 1st image at 30 degree 2nd on 60. how can we use filtered back projection to create 3D volume from these 12 images

Extreme helpful

Great job, thanks a lot.

Thanks a lot Dr. Samuli 🌹

Thanks great video. Can you explain what is the matrix P? is it a probability matrix? If yes, probability of what?

Thanks for brief explanation

How is your result=A\v working I got an error because my A and v matrices dimensions didn’t agree

Great lecture!

WOW! Thanks a lot man!!

HJajs

wow amazing. thank you for sharing the knowledge for free. Sir I have become a fan.

Can you pass me the code for it?

how do you manage the geometric calibration of the micro-CT system?

i'm trying to write a matlab code employing this so thanks man :)))))

Thanks for sharing that, it’s soooo useful!

Samuli you are amazing !

my professor said I should watch this and I´m not disappointed

thanks

His ascent tho 🤣🤪

Can you please share the code as a link or add it to the description?

Wow!

Very Good, Do you have the .m file

Katsoin ekan videosi, kun Kauppalehti optiossa kerroit kanavastasi. Erittäin hyvää kansanomaistamista. Neliöjuuri oli ihan tuttu juttu, mutta nyt siihen sai uutta perspektiiviä. Thanks.

Kas. Joskus 90-luvulla kokeilimme samaa elektroniikan dynamiikan kasvattamiseen: ns. translineaariteorian mukaan likimain eksponentiaalisesti toimivista (Ic ~exp(Ube/25 mV) bipolaaritrankuista voi rakentaa vaikka minkälaisen laskukoneen. Neljästä transistorista teimmekin analogisen sqrt-kompressorin, joka oli muodoltaan ihan oikean oloinen, mutta sen tarkkuus oli pahasti sinne päin: kompression purkaminen digitaalipuolella oli myöskin sinne päin.
