Hey! You're saving my life, literally! I'm gonna have my first Image Processing's exam in two weeks, and I hadn't understood anything till I found your channel! You're a MVP! Now, I finally have an idea about what are all those concepts and formulas!
Thanks a lot! I definitely subscribe!
zombie apocalypse in the background , but ma'am still teaching. #RESPECT
Sahi bola bhai 😂🤣🤣
Astaghfiruallah Brother its Azaan Respect Other religion
background may namaz padi ja rahi hae baas!😂🤣
None of the other videos have examples except yours. Thanks, this will save us in exams...
Respected Madam,
Yours explanation is so easy to understand. Thank you madam.
Thank you😊
At 16:51 center will be 100*(-8).
And thank you very much, you are saving my semester.
why azan in every video...is your lecture shooting time and Azzan time same?? But still good work...
love the way you speak your name and when you say here
there is a doubt, 450+300-400 = 150? it should be 350
and also 150+500-400 = -150? it should be 250
did you use some different method or is there any rule followed.
Any one can solve this problem ?
Made the concept very easy to understand 😇
Your efforts are tremendous!
My suggestion to you start the series of episodes with practical knowledge,
Start with analog image, and end with analog image (degital copy of analog image)
Not only students but anyone wants to know about this can easily understand!
I mean to say, image, camera sensor, ADC, memory, print etc must be involved.
Huge Thanks to you madam!
Thanks sister for saving us this time ❤️
Thank you very much.
Tqsm for ur explanation,itz really outstanding maam
18:09
We know that we have +ve intensity values (0- 2^n-1). Right!
In the output image, we have few negative values, so shall we round them off to 0 as we did in previous few lectures?
yes bro
can you explain why in Q3 you have take that operateor ?
and why not -4 centre operator?
please do reply... i have my exams
MashaAllah azan b horaha hy
Can we replace the negative intensity values with 0?
GREAT THANKS !!!!
In Ques. 2; We'll get output as -20 if apply the enhaced filter with -5 as center but with other mask, the answer is -24 as shown by you. Then which one is correct ??
nice presentation
In Q.3 there is a small calculation mistake . When shifting the mask 3rd time ( 50 * 5 +100 * 3 - 50 * 8 )
= 250 + 300 - 400
=150
instead of 250 by mistake you have written 450.
if the center pixel is increased by 1 then its value would be -3 and -7 as given in the example
maam which video is for smoothing frequency domine filter-sharpning filter domine filter
❤️🙌❤️
16:11
How is that 450?
Why did you stop making videos they are helpfull
what do you mean by -ve pixel value after applying the filter ?
why didnt you do zero padding maam ? at 13:00 ????
16:17 that is not 450 ......50×5=250...... otherwise excellent playlist ma'am.....
Mistake at 16:24 and 17:21. Thus the result image is wrong.
Thank you so much for pointing this out. The values would be 350 and 250 and therefore the final image would differ accordingly. I hope that you understood the concept though :)
@College Friendly Thank you for detailed explanation. But sharpen_image = original_image - filtered_image. Here, you only determined the filtered_image, not the sharpen image. This actually made some confusion. Keep posting.
@@atikhasan4358 @College Friendly we have to subtract the original image from the filtered image to get the final sharpened enhanced image right?
Here we have to do convolution for center pixel only ?
thanks girl....its a real help
NAAGESWAR MURMU...CASI HOW'RE YOU BROTHA
i guess ma'am u have made mistake in q3
50*5=250 but u have written 450 and calculated accordingly
in Q1 we got -14 but i guess we will have to write 0 because gray level value cant be negative
Yeah, same in Q2 too.
MAAM CAN YOU UPLOAD BAYS THEOREM?
Maam method of convolution is different in video 11
Ma'am pls thoda volume badha dijiye video me without earphone sunai nhi deta
All good but audio is less
In the laplacian filter ex where we got -14, we've to write 14. right?
I guess we'd have to write 0.
However I'm not sure man.
Pls Upload Notes Also
you are teaching the best !!! but you got confused in this sum due to numbers .....your answer is wrong
be loud madam
cancer is everywhere
Calculations toh theek kiya karo
50*5 = 250 not 450
ma'am are you single
