CStats:Median

CStats:Median and CStats:MedianSdev

The Median method computes the median value a data object or a list of numbers. The array and list parameters must contain a mixture of numbers and strings that can be converted to numbers.

Syntax

nMedian = CStats:Median( CImage, CRect )

nMedian = CStats:Median( CImage )

nMedian = CStats:Median( table )

nMedian = CStats:Median( n1,n2, n3, ... )

nMedian, Sdev = CStats:MedianSdev( CImage, CRect )

nMedian, Sdev = CStats:MedianSdev( CImage )

nMedian, Sdev = CStats:MedianSdev( table )

nMedian, Sdev = CStats:MedianSdev( n1,n2, n3, ... )

CRect is a bounding rectangle for the CImage objec.

table is a 1-dimensional array containing numbers.

n1, n2, n3, ... are numbers or string values that can be converted to numbers.

On success, returns the median and standard deviation.

On failure, returns 0, 0.

Example

Suppose a CImage named I and a CRect named R exist. The following script returns the median inside a rectangle on the image:

S = new_stats()	-- create a CStats object
-- specify CImage and CRect to measure
nVal = S:Median(I, R)	-- returns the median
Printf("Median=%lg\n", nVal)	-- list the results
S:delete()	-- when done with S, remove it from memory
