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 )

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
