2-6-1-1 Contour Enhancement
When an image is blurred by the boundaries between image grains becoming unclear, it can
be sharpened by applying contour enhancement. Five types of filters are provided for use in
the contour enhancement.
1 Laplacian filter
This filter enhances the contours of the image grains. If the image contains noise, the noise
is also enhanced. By adding the original image to the image processed with Laplacian
filtering, it is possible to obtain an image with stronger contour enhancement. The filter
format is as shown below.

1.
Display the image window of the image to be processed with Laplacian filtering.
2. When the image is composed of multiple image slices, the range of image slices to be
filtered can be specified using the <Set start position> and <Set end position> buttons
above the image. First display the image slice to start filtering using the <Display>
button and click the <Set start position> button. Then, set the image slice to end filtering
in the same way as above.
3. When the image to be filtered was acquired in the multi-channel mode, filtering is
applied only to the channels being displayed.
Example) When only the Ch1 image is displayed, filtering is applied to the Ch1 image
only.
For the switching of channels, see section 2-4-3, “Switching the Display
Channels”.
4. Click the <2D Laplacian> button. A new image window having the page tab named
[Filter] appears, showing the filtered image.
During filtering, the status bar shows the progress of processing.
