Frequency domain filtering in image processing - Low pass and High pass filters

This video talks about frequency domain filtering. It explains the various types of smoothening (low-pass) frequency filters and sharpening (high-pass) frequency filters along with a numerical towards the end.

[@vaibhavmaheshwari7686]

In the question where we have to apply ideal low pass, you wrongly applied the formula.. result will be 1 when D(u,v)

[@vaibhavmaheshwari7686]

Pls check at 17:35

[@amishamundra2000]

Mam you can 7.11

[@daimraza3271]

yes you are right

[@Nitish.Singhal]

Superb work . What an explanation . You saved my final exam .😘

[@collegefriendly]

Thank you Nitish😊

[@alexmercer7795]

Tujhe UP bulati hai

[@metateamwork]

Maam, you use the Ideal High Pass formula in Ideal Low Pass, according your solution the image is sharped not smooth and the ideal low pass filter is used for smooth/blur the image

[@ARkhan-xw8ud]

Yes, she used high pass filter and it will sharp the image

[@nisarshinwari9213]

Superb explanation but a little mistake in a question solution the scenario is for ideal high pass not low

[@sahilkhan_cs50]

In 20:30 there is mistake in value of root(8) that will be 2.83 instead of 4.24.

[@karthikeyanr6321]

When do we need to perform pixel by pixel multiplication and normal matrix multiplication?

[@arjunsharmapoudel4099]

mam you have use formula of high pass ideal filter instead of low pass ideal filter. please look at 17:43

[@IWillBiteYourSoul]

sahi keh raha hai bhai

In caption, it says "this is anushka risky" 😂😂

[@sussybaka4200]

[@Xoro162]

your tutorials are so awesome

[@harshveerthind3627]

how did we get the kernel for step 2?

[@harshareddie-de5ty]

yeah it too didnt get it ?

[@JagritiShukla-jt5vh]

Where we need to apply matrix multiplication and where pixel by pixel, how you decide? Can anyone explain

[@chidanandskusur4054]

Respected Madam, One doubt in this lecture, In Problems. 2nd step While calculating DFT In Kernel, I and j means? How? We got result? Like 8 in the result? In free time, you can reply madam.... Thanks lot madam. 🙏🙏

[@Hamza_BioMed_Learning]

J is a complex number, imaginary part. 8 comes after the matrix multiplication. We do matrix multiplication instead of pixel by pixel multiplication.

[@piyushmishra114]

Well done Ma'am............. 🙏🙏🙏🙏

[@shrirangjoshi6981]

Thank you ma'am excellent explanation !!!

[@chidanandskusur4054]

Thank you madam. I have understood.... 🙏🙏

[@zhiabookbindingstudio]

This really helped me, thanks alot❤️

[@user-hc8zq6xb2i]

a small doubt that how do we got the kernal you used for applying DFT? please explain me anyone... BTW explanation is good.

[@rutulprajapati8282]

Madam, How to apply 2×2 Smoothing filter on 5×5 image...? Please help 🙏🙏🙏🙏

[@sahalpathan5980]

Please Mam, ideal low pass filter Equation is wrong. Kindly update it , it should be 1 for 0

[@daimraza3271]

yes you are right

[@dungle-ck8xp]

in 16:18 I think the result of calculating the 2 matrix is wrong

[@ahmadfawadawan2405]

after multiplying with kernel what's the value of "j" so "8" howww??? @17:30

[@prakruthitambi9676]

Thank you mam ❤❤

[@rushikeshjadhav6346]

nice explanation!

[@asheeshsharma7808]

You have a very sweet voice...

[@gantakrishnasaikoushik1904]

what is kernal how to get kernal??

[@hamzaamir3305]

Where did you get the IDFT kernel from?

[@deepali8282]

Did you get the answer?

Hi, can you pls share your Notes over a google drive?

Thank you mam!🤩

[@collegefriendly]

Welcome😊

[@hardikpandya2841]

you must have chosen "Professor" as your profession

[@wolfie8748]

17:12 how does the first one is 0? isnt 1x1x1 = 1

[@adityachougule8176]

in fourier tranforms we use matrix mulitplication,in spatial we use pixel value matrix multiplication

[@vardhangamechanger6544]

such a good voice ,wana see your face .... mam😅😅😅😅

[@abdulvahapbenli9502]

ty madam

[@anandkumar-rm2im]

Why u using high pass. Filter instead of low pass filter in solution 20:12

[@UrReelGuy]

Wrongly Ideal high pass filter is applied, which should be corrected

[@radhasingh3549]

value of j?

[@A_venugopal]

can u provide the notes of the complete playlist mam

[@jk-sm6qr]

Thanks

[@dilwaralam8461]

PLZ CHECK matrix multiplication G(u,v) i think that is wrong

From where this mask cme

[@collegefriendly]

You will have to by heart the different masks in advance. Try watching the previous videos in the series to get more clarification

[@swantarya8433]

7:29 that's not how frequencies work.
