[mmsubm] [Up] [mmunion] Operations

mmsymdif
Symmetric difference between two images

Synopsis

y = mmsymdif ( f1 , f2 )

Input

f1 Image Gray-scale (uint8 or uint16) or binary image

f2 Image Gray-scale (uint8 or uint16) or binary image

Output

y Image

Description

mmsymdif creates the image y by taken the union of the subtractions of f1 from f2 and f2 from f1. When f1 and f2 are binary images, y represents the set of points that are in f1 and not in f2 or that are in f2 and not in f1 .

Examples

Gray scale image:
a = uint8([1, 2, 3, 4, 5])
b = uint8([5, 4, 3, 2, 1])
print mmsymdif(a,b)
[4 2 0 2 4]
c = mmreadgray('tplayer1.tif')
d = mmreadgray('tplayer2.tif')
e = mmsymdif(c,d)
mmshow(c)
mmshow(d)
mmshow(e)
c d e
