FIND_CENTER

FIND_CENTER

Name


    FIND_CENTER

Purpose


    This function will look at a cluster of pixels in a
    binary image and determine the mean coodinate of
    that cluster. It is assumed that there is only ONE
    cluster of pixels in the provided image. If there
    are more, then the mean coordinate of ALL cluster
    pixels will be returned, which is probably an
    undesirable result.

Category


    Image Processing.

Calling Sequence


    Result = $
      FIND_CENTER( clusterImage )

Return Value


    This function will return a 2-element vector containing the
    centroid coordinate for the provided cluster of pixels or a
    scalar value of -1 if a single point or fewer was provided.

Inputs


    clusterImage:
      A binary image containing a cluster of pixels for
      which the mean coordinate (centroid) is to be
      computed.

Keyword Parameters


    None
