Implemented in Python.
| f | Image Gray-scale (uint8 or uint16) or binary image. |
| SEQ | String Values: "OC" or "CO". Default:
|
| b | Structuring Element Default:
|
| bc | Structuring Element Default:
|
| n | Double Non-negative integer.
(number of iterations). Default:
|
| y | Image Gray-scale (uint8 or uint16) or binary image. |
mmasf creates the image
y by filtering the image
f by
n iterations of the close by reconstruction and open by reconstruction alternating sequential filter characterized by the structuring element
b. The structure element
bc is used in the reconstruction. The sequence of opening and closing is controlled by the parameter
SEQ. 'OC' performs opening after closing, and 'CO' performs closing after opening.
def mmasfrec(f, SEQ="OC", b=None, bc=None, n=1):
from string import upper
if b is None: b = mmsecross()
if bc is None: bc = mmsecross()
SEQ = upper(SEQ)
y = f
if SEQ == 'OC':
for i in range(1,n+1):
nb = mmsesum(b,i)
y = mmcloserec(y,nb,bc)
y = mmopenrec(y,nb,bc)
elif SEQ == 'CO':
for i in range(1,n+1):
nb = mmsesum(b,i)
y = mmopenrec(y,nb,bc)
y = mmcloserec(y,nb,bc)
else:
assert 0,'Only accepts OC or CO for SEQ parameter'
return y
