Filter List and Edit Panel
In the
Filter List
panel, the filters and the matrix size (
Kernel Size
) are selected.
The matrix of the selected filter and the set filter parameters
Factor
,
Divisor
and
Offset
are displayed in
the
Edit
panel.
(1) Kernel
Size
The size of the filter matrix can be modified here.
The effect of a filter increases along with the
matrix size. However, this also increases the time
required for filtering.
•
Select the required matrix size by clicking on
one of the selection buttons
3 x 3
,
5 x 5
or
7 x 7
.
(2) Lowpass
filter
With the lowpass filter, the gray value of each
center pixel is replaced with the average value of
the surrounding neighbor pixels. The viewed
neighbor pixels are defined by a square. The
modified pixel now is the center pixel of the filter
matrix.
Image noise will be reduced by the application of
the lowpass filter. The cutoff of regions will blur.
Local maxima will be flattened. The dynamic range
will be reduced considerably.
This filter permits the matrix size to be modified
only in the 3 preset steps.
