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( method )

CImageSet contains the collection of images to be combined.

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

Remarks

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

Method	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 fragment uses SetNormMethod to specify that the images are to be scaled to bring them into normalization:

C = CImCombine:new()	-- create a CImCombine object
R = CRect:new(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
C:delete()	-- when done with S, remove it from memory
