Hello,
In the 3rd exercise it was mentioned that :
"Then, the sharpening filter is defined as , where
is a
Kronecker delta kernel with a values of 1 at the diagonal elements and zero elsewhere"
I expected delta to be the Identity matrix, but in the correction it is instead the matrix [[1,0,0], [0,0,0],[0,0,0]], using the same matrix as in the correction yields better results and I was wondering whether it was a choice to improve the results or is the matrix just meant to be [[1,0,0], [0,0,0],[0,0,0]]? (using an identity matrix gives a less clear image)
Thank you for your time
