Was searching for a good video with an example from around 20-30 minutes. This is the best!

[souvikkhanagwal]

just watched till this video for my mid sem.
got the same question od distances in exam aced it thanku <3

[subhajitdas]

You are a god ma'am...Tomorrow I've my DIP exm and thanks to your playlist I've understood all the problems well....Great work ma'am...

[pavankumar]

You are a gem mam..cant describe your work in words..thanks for your effort. You surely deserve lot more subscribers

[shanukvinod]

Thank you mam for these classes,
Tomorrow I am having my dip exam and because of your class i am able to cover topics fast 🙂

[PrathamDarpanJaulkar]

literally i've watched multiple videos regrading this topic and coudn't understand but now i understood it very well Thanks mam

[shoryapawar]

Thankyou for this playlist ma'am .
It is helping me a lot for the academics purpose

[junaidshahzad]

maam your lectures are amazing and very very helpful, i am so much thankful to u, u are the best teacher.

[billwhoever]

Ty for the easy to understand explanation, wasn't taught about these filters and could not understand how it worked when it was mentioned in a paper.

[hazareroglu]

We only consider the X positions (horizontal )right do not calculate for the y(verticle). I consider like that because the filter you used actually the convolution of the original types for X. I hope I could explain myself

شكرا جزيلا على كل فيديوهاتكم، المادة نفسها و الشرح بسيط يفهم.

[AbdurRehmanSaleem]

can you please tell why pixel (1, 1) is not the first 50 @top left corner??? is the replication padded is already done?

[itv]

Aren't we required to use both horizontal and vertical edge detection operators so that we're able to find gx as well as gy to compute the gradient?

[adnansami]

Alhamdulillah, you explained everything so simply! I have an exam on this tomorrow and this is helping a lot!

[JitusVlog]

What about zero padding???? In case sobel and prewit. Like when we are calculating magnitude of gradient of given input image using sobel or prewit???

[subashadhikari]

Thankyou so much from the land of mountains, Nepal

[khaledibrahim]

If he gives me an image ( numbers) and ask me to generate gradient image how I will do it?

[abdallah]

Thank you very much dear, the explanation is very clear and simple

[pranavkhurana]

Really nice! Looking forward to more such amazing videos🙌

If pixel is not given then what we have to do
