•
Activate
ICS
in the
Processing
tool by clicking
on the arrow.
The
ICS
menu will appear with three sub-
processing functions:
Remove structures
,
ICS
correlation
and
Map filter
(Fig. 119).
5.3.8.1
Remove Structures
•
Activate
Remove structures
in the
ICS
tool.
The
Remove structures
menu will appear
(Fig. 120).
•
To select an image, press the
Select
button and
click into the image in the container. This will be
your
Input
image.
As an output image an image with the selected
average subtracted is computed and the result
presented in the
Preview
window.
•
If the
Apply
button is pressed, the averaged
subtracted image stack will be opened as a new
image in the container.
You have four options that can be selected via the
Remove Structures
pull down menu (Fig. 121):
None
,
Slowly moving structure
,
Immobile
structures (+Stack)
and
Immobile structures
(+Plane)
.
If
None
is selected, no average will be subtracted
and the original image is kept. If
Slowly moving
structure
is activated the
Average frames
input
box becomes available. Type in the required
number (minimum is 2) or use the slider or arrows
for input. The number defines the number of
frames that will be averaged and subtracted in a
gliding way from the original stack in the following
way:
•
From a stack of n frames take successive m
moving average frames with an overlap of m-1
and average these. The outcome is a new stack
with n-m+1 gliding or moving average frames.
Calculate from each of the average frames the
overall average of all pixels, which is a scalar.
•
Subtract the i-th of the gliding average frame
from the (i-1)+m/2 original frame and add the
i-th scalar. In this way, the first frame to be used
from the original stack is m/2 and the last
m/2+(n-m+1). This creates a new stack of n-m-1
frames that is the output image.
