Two byte image datasets
256 by 256 histogram image. The DN at Line i, Sample j corresponds to the number of pixels with DN j-1 in Input 1 and DN i-1 in Input 2.
The portion of the inputs to be used, if not the entire image.
The first image line to be used.
The first sample to be used.
Number of lines used.
Number of samples used.
By default, the output is normalized by dividing each population by the
population Nth most populous value, as specified by the NORM parameter, then
multiplying by 255.
If the ROOT keyword is used, the square root is taken prior to multiplying
by 255. This has the effect of compressing the high values and expanding the low
values.
If the NONE keyword is used, no rescaling or normalization is performed.
The output is the number of pixels in each population. When NONE is specified,
the output is fullword integer, otherwise the output is byte.
This parameter is analogous to the SPIKES parameter in HIST (and
elsewhere). The N most populous values are set to 255, and all other values
are rescaled to be in the proper proportion to the Nth most populous value.
To form the histogram, only every nth sample of every nth line is used, starting with the first sample of the first line. INC=n has the same effect as LINC=n and SINC=n. The specification of INC will override the values given by LINC and SINC.
To form the histogram, only every nth line is used, starting with the first line.
To form the histogram, only every nth sample is used, starting with the first sample.
