Show that $1-$pixel thick lines in images can be detected with the help of the mask given below. Which directional lines can be found with this mask? On binary line segments Make your proof by using the answers given by the mask. A total of four basic directions $($horizontal$,+45\backslash$deg $,$ vertical

and $45\backslash$deg $)$ write down the other masks with their coefficients to be used to find the lines.
