backgrounds         determine averages of subareas

 

PURPOSE: Determine the average background of an image that is uneven.
         The program picks 4 square areas (at this time) at a specified
         distance in x, -x, y, -y from a user defined center and determines
         the median of the average values. 
           
USAGE:        backgrounds

        .Input file: image001
        [Enter the name of the large input file.]
        
        .Center x,y, distance from center: 257,257,50
        [Specify image center, and how far the four subimages should
         be away from this center (cento to center measurements).]
         
        .Box dimension: 50,50
        [Enter the dimensions of the boxed out subimages.]
        
        .Enter variable to receive output: v.avg
        [Enter the varaible name for a named tuple to recieve the median
        average and sigma. Default name v.back.]
        
        .First output file or *: litwin001
        [Optionally provide an output file name and the four windows will be
         written out. Numbering will be from 1-4.]
