Question $1$:

$=>$ Consider the following image and for boundary pixels $($red$,$ green$)$ use a $3$x$3$ filter

with zero padding $($ Hint: place the center of the kernel on the required pixel $)$

What are the three conditions when the target pixel is at the boundary while

filtering?

Compute the MIN filter based on the second and third boundary conditions?

Compute the MAX filter based on the second and third boundary conditions?

Compute the special case rank filter based on the third boundary condition?

Compute the $9$th$-$order rank filter based on the third boundary condition?

List the steps of applying a rank filter?
