Lecture 2 Image Digitization I

[@hwaakthuu]

right ear feels blessed

[@USJ2020]

Thank you Prof Biswas! very clear!
I have spent 1 day reading it by myself which I couldn't understand. But you make me understand it easily now.

[@j0hmama]

This has helped me understand the vocabulary used in image processing.

Delivering qualitative knowledge... Very good lecture sir

[@vanessaingrid7582]

You are such a good lecturer!! Perfect!

[@arun090993]

thank you for every one who made this video lectures.

If anyone else was confused at 29:40 like me he is not finding the fourier series of the delta function (which would be impossible as it is not periodic) but finding the fourier series of the comb function.

[@DHEERAJkumar-xt3yn]

@10:20 there should be f(M-1,1), f(M-1,2)...........f(M-1,N-1)..

@nptelhrd the audio is only on one channel :)
People facing problem switch to Either Mono left or right !
Mono Right worked for me :)
Awesome lecture :)

[@divyapoojary3262]

Viraj Shelke how to fix this plz help

[@brushmandroid]

@14:50 Some Old technique! You don't have to do the DA conversion before presentation on a display anymore!! How old is this?

[@anshumansinha5874]

@23:43 shouldn’t it only be Xs(t) = Sum (0: inf) [ X(mΔt) ] ?

[@raghav429]

thank you very much prof.biswas

Helpful lecture series

[@roboti-cist6697]

Thank you for this lecture. could you please get more examples

[@jingweixuan395]

Very good ,thanks

[@LinLang2007]

The audio is only on one channel, just FYI.

[@MuditGupta]

thnks professor :)

[@don2186]

At 43.13 min.. Isn't the Fourier transform of the convolution equal to product in frequency domain?

[@brushmandroid]

any answers to the questions presented at the end??

[@narayansuthar3368]

Thanks!!

[@強健控制實驗室]

Am I wrong? Diract delta function should be infinite at one point and be zero for others?

[@inderpreetsinghchhabra6926]

it is but only in the continous time domain whereas in discrete time domain it has a specific value at the point of existence

[@bharadwajaryasomayajula7887]

Then it should be called Kronecker Delta...

[@atchutram9894]

Your answer only confuses. In the present context the lecturer is wrong. Straight and simple. Sampler should have train of impulses where each impulse have unit energy. Discrete domain is irrelevant.

[@mukeshtripathi2268]

thanks a lot sir...

[@kankipatishiney2209]

thank you sir

[@ashokaarya2238]

nice lecturer but its too long boring but have a nice and usefull information
