Implemented in Python.
f1 | Image Gray-scale (uint8 or uint16) or binary image. |
f2 | Image Gray-scale (uint8 or uint16) or binary image.
Or constant |
f3 | Image Gray-scale (uint8 or uint16) or binary image.
Or constant. Default:
|
f4 | Image Gray-scale (uint8 or uint16) or binary image.
Or constant. Default:
|
f5 | Image Gray-scale (uint8 or uint16) or binary image.
Or constant. Default:
|
y | Image |
mmunion creates the image
y
by taking the pixelwise maximum between the images
f1, f2, f3, f4,
and
f5
. When
f1, f2, f3, f4,
and
f5
are binary images,
y
represents the union of them.
>>> f=uint8([255, 255, 0, 10, 0, 255, 250])
>>> print 'f=',f
f= [255 255 0 10 0 255 250]
>>> g=uint8([ 0, 40, 80, 140, 250, 10, 30])
>>> print 'g=',g
g= [ 0 40 80 140 250 10 30]
>>> print mmunion(f, g)
[255 255 80 140 250 255 250]
>>> print mmunion(f, 255)
Warning: Converting input image from int32 to uint8. [255 255 255 255 255 255 255]
