#!N #!N Functional Details #!N #!N This module applies one of 
the following binary morphological operators to input data: #!CForestGreen #!N #!N 
 #!F-adobe-courier-bold-r-normal--18*   #!N "close" "dilate" "erode" "open" #!EF #!N #!N #!EC The 
input data are treated much as booleans are in the C 
language (e.g., 0 = FALSE and nonzero = TRUE). #!N #!N 
The  #!F-adobe-times-bold-r-normal--18*   mask #!EF parameter (see below) is centered on each 
position in  #!F-adobe-times-bold-r-normal--18*   input #!EF in turn, and all positions corresponding 
to "1" in the mask are considered for  #!F-adobe-times-bold-r-normal--18*   operation #!EF 
(see below). #!N #!I0 #!N #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   input 
#!EF #!EF #!I50 #!N is the input data to be operated 
on. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   operation #!EF #!EF #!I50 #!N 
specifies one of the following: #!N #!I0 #!N  #!F-adobe-times-medium-r-normal--18*   #!N #!N 
#!I30 #!N o "dilate": The output corresponding to a given data 
value is true (1) if any data value in  #!F-adobe-times-bold-r-normal--18*   input 
#!EF corresponding to a "1" in  #!F-adobe-times-bold-r-normal--18*   mask #!EF is true. 
Otherwise, the output is false. #!N #!I30 #!N o "erode": The 
output corresponding to a given data value is true (1) if 
all the data values corresponding to a "1" in  #!F-adobe-times-bold-r-normal--18*   mask 
#!EF are true. Otherwise, the output is false. #!N #!I30 #!N 
o "close": is dilation followed by erosion. #!N #!I30 #!N o 
"open" is erosion followed by dilation. Note: Successive openings or closings 
have no additional effect. #!N #!I0 #!N #!EF #!N #!N #!I0 
#!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   mask #!EF #!EF #!I50 #!N specifies one of 
the following: #!N #!I0 #!N  #!F-adobe-times-medium-r-normal--18*   #!N #!N #!I30 #!N o 
a Filter name (see  #!Lfilter,dxall849 h Filter  #!EL  ) #!N #!I30 #!N o an 
explicit matrix. #!N #!I0 #!N #!EF #!N The function of both 
is to identify potential operands for  #!F-adobe-times-bold-r-normal--18*   operation #!EF (see above). 
The dimensions must be odd, and the default is the 3 
* 3 box filter of Filter. #!I0 #!N #!N #!N #!N 
The module supports all data types and, like Filter, requires regular 
connections (quads or cubes). It handles both position- and connection-dependent data. 
#!N #!N If the data are vectors, each element of a 
vector is transformed independently. Because the module returns a 0/1 output, 
its output is always TYPE_UBYTE. Note: Data along the boundary are 
replicated to fill the overlap region for the filter. #!N #!N 
Components #!N #!N Modifies the "data" component. All other components are 
propagated to the output. #!N #!N Example Visual Program #!CForestGreen #!N
