low |
float |
lower limit of data range |
high |
float |
upper limit of data range |
Output Ports
Description
IPhistogram constructs the histogram of an image and outputs an array of size nbins whose values are the counts of the occurrences of each value. It has lower and upper limits and a region-of-interest control.
Input Ports
-
src
-
A reference to an ip_Image.
-
roi
-
A reference to an optional ip_Roi. The data must be of type byte.
Parameters
-
nbins
-
The number of bins to count over.
-
low
-
The lower limit of the data range to be counted.
-
high
-
The upper limit of the data range to be counted.
Output Ports
-
nbins
-
The input parameter exported as an output port for convenience in linking with downstream modules such as the uniform scalar field Field Mapper.
-
bins
-
An array of integers, nbins long, whose values are the histogram counts. The uniform_scalar field mapper can convert this output into a field for subsequent downstream processing.
