STRING - INP=A where A is the input dataset name.
STRING - OUT=B where B is the output dataset name.
4 INTEGERS - SIZE=(SL,SS,NL,NS) where SL is the starting line, SS is the starting sample, NL is the number of lines output and NS is the number of samples output. (SIZE is usually defined as SIZE=(1,1,NL,NS)). Default is taken from the VICAR label within the program.
INTEGER - NL=N1 where is N1 is the number of lines output.
INTEGER - NS=N1 where is N1 is the number of samples output.
INTEGER - NLW=I1 where I1 is an integer and specifies the size of the filter kernel in lines. NLW should be an odd integer; if it is not, the program uses the next larger odd integer. Default is NLW=11.
INTEGER - NSW=I2 where I2 is an integer and specifies the size of the filter kernel in samples. NSW should be an odd integer; if it is not, the program uses the next larger odd integer. Default is NSW=11.
KEYWORD - Valid:('HIGH) 'HIGHPASS specifies that the output is to be in
highpass format, i.e., the input minus the local median value. Default
is the lowpass mode.
DCLEVEL is a constant added to all pixels prior to output, when in the HIGHPASS mode. It is most commonly used to rescale byte data back into the 0 to 255 range.
REAL - PERCENT=R4 where R4 is an floating point number and specifies the percentage of the filter window values which are less than or equal to the output value. The default of PERCENT=50.0 specifies that the true median value of filter window is to be found, whereas if a lower (or higher) value is specified, the output value will be somewhat lower (or higher) than the actual median.
DCTRAN is a scaling factor, used in the HIGHPASS mode, when the user desires
to add back part of the input image to the output. In the HIGHPASS mode
OUTPUT = INPUT - MEDIAN + (DCTRAN*INPUT) + DCLEVEL
