CImCombine:Sdev
The Sdev method creates an image who's pixel
values are the standard deviation of values among all images at
each point.
Syntax
|
CImage = CImCombine:Sdev( CImageSet )
|
CImageSet contains the collection of images to be
combined.
CImage is a new image created by this method.
On success,
this method returns a new
CImage.
On failure,
this method returns
nil.
Remarks
Each pixel in the output image is the standard
deviation of values at the same location in all the images of the
CImageSet. This is not an image like each of the source images, but
is a statistical map over the surface of the collection of images.
Depending upon the images and the application, you may or may not
wish to normalize the images before computing the range.
Example
Suppose a
CImageSet named S exists. The
following script combines the images by the Sdev method
after normalizing their luminance by the median statistic computed
inside the central 10% of the image:
|
C = new_imcombine()
|
|
|
R = new_rect(10,50,10,50)
|
|
|
C:SetRelRect( R )
|
|
|
C:SetNormStat("median")
|
|
|
C:SetNormMethod("scale")
|
|
|
I = C:Sdev( S )
|
|
|
I:Display()
|
|
|
C:delete()
|
