"he was not a modest person but he did lots of good contributions" - that says a lot :P really great video, nicely explained. thank you :)

Really useful lecture. Great explanations! Thank you so much for uploading this!

i love the explanation even included the math function but it is still easy to understand.

I cant understand why he is applying the smoothing kernel in y direction but the derivative kernel in x direction in x direction while detection of horizontal edges?Shouldn't the derivative filter also be applied in y direction since gradient changes perpendicular to the direction of the edge?

Great explanations thanks!

Great explanation of sobel, thanks!

[@arsalanarxal4063]

hi how we apply thresholding on slope in Marr Hilderth ? what is value of thresholding ?

[@vivekshah2867]

awesome explaination.

[@weightednormal3682]

I was looking at a sobel kernel the other day and couldn't understand it's construction. Now I understand it was a gaussian derivative.

please Dr .where can I get slide for this lecture

[@mohamedsayeedkhan1882]

Sir.,let Forward the presentation of this topic .....please sir., Because it's much more use to overview the video us easy to revise....

1:04:00 - I don't understand what's the x-axis in this image. Can someone elaborate ?

[@baskaisimkalmamisti]

Gradient magnitude plot of one row of edge map image matrix of the image. So, x is the index of the element in the row.

[@hussienalbared8046]

Are the slides available

[@usharanibandi8667]

sir, can you give me code for sobel edge detection in Verilog by using FPGA Or can you give elated books sir..
