FIND_CLUSTER_CENTERS

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.

Side Effects


    None

Requires


    FILL_REGIN
    FIND_CENTER
