Session 17 - Sobel Edge Detector - A Quick Understanding

Here, we establish a quick understanding of what Sobel Edge detector is all about.

[@mischahogendoorn9788]

When you applied the Sobel filter, you perform a correlation, not a convolution. If you want to perform a convolution with the kernel, you will have the dot mirror the kernel first (and than the calculation you performed is correct).

Hello !! How did you get x and y derivates ?

[@hasanshahriarboni7957]

sir, How do you find x-derivative and y derivative?

[@samrs007]

At 06:28, Is the threshold value of 5 a fixed value or can it be changed? Can the threshold value be modified as per our requirements? Could you clarify this in details.
