Determine whether filter coefficients are separable
S = isfilterseparable(H)
[S, HCOL, HROW]
= isfilterseparable(H)
takes
in the filter kernel S
= isfilterseparable(H
)H
and returns 1
(true)
when the filter is separable, and 0
(false) otherwise.
[
uses the filter
kernel, S
, HCOL
, HROW
]
= isfilterseparable(H
)H
, to return its vertical coefficients HCOL
and
horizontal coefficients HROW
when the filter
is separable. Otherwise, HCOL
and HROW
are
empty.
