2D filtering
A 2D
image f[i,j] can be filtered by a 2D kernel h[u,v] to produce an output
image g[i,j]:
This
is called a cross-correlation operation and written:
h
is called the “filter,” “kernel,” or “mask.”
The
above allows negative filter indices.
When you implement need to use: h[u+k,v+k] instead of h[u,v]
