CImCombine:SetNormMethod

The SetNormMethod method sets the method used to normalize the images to match the reference image. The options are "scale", "offset", and "none".

Syntax

CImCombine:SetNormMethod( sMethod )

where

CImageSet contains the collection of images to be combined.

sMethod is a string describing the normalization method (see below).

The normalization method describes the way the images are adjusted to match the reference image. The options are described in the following table:

Normalization Methods

Name	Description
none	No normalization is performed.
scale	The images are multiplied by a factor.
offset	The images are offset by a constant value.

Example

The following script uses SetNormMethod to specify that the images are to be scaled to bring them into normalization:

C = CImCombine:new()	-- create a CImCombine object
R = NewRect(10,50,10,50)	-- central 10% of the image
C:SetRelRect( R )	-- specify CImage and CRect to measure
C:SetNormStat("median")	-- use median as the normalization statistic
C:SetNormMethod("scale")	-- scale to normalize the image set
I = C:Mean( S )	-- combine the image set, return a new image
I:Display()	-- show the new image
