CStats:Median

CStats:Median

The Median method computes the median value inside a rectangular region of the image. The rectangle and image must have been previously initialized for the CStats object.

Syntax

nValue, Sdev = CStats:Median()

On success, returns the median value as a number.
On success, the second returned argument, Sdev, is the standard deviation about nValue
On failure, returns 0, 0.

Example

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

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