FIND_CLUSTER_CENTERS
Name
FIND_CLUSTER_CENTERS
Purpose
This function will find the centroid coordinates for clusters
located throughout a provided image. The clusters will first
be refined by thresholding the provided image using the
supplied digital count threshold value.
Category
Image Processing.
Calling Sequence
Result = $
FIND_CLUSTER_CENTERS( image, $
threshold )
Return Value
This function will return a 2xN array of cluster centroid values
that have been located in the thresholded version of the image
provided.
Inputs
image:
An array containing the clusters of points for which the
centroid coordinates are to be found.
threshold:
A scalar defining the digital count threshold to be used
in the creation of the binary version of the provided array.
Keyword Parameters
NONE
Return Value
This function returns a 2xn array containing the cluster center coordinates
for the clusters identified by this routine.
