Download: |
motion_deblur.zip |
Installation: |
Download and extract the contents of file
motion_deblur.zip and
simply put "Motion_Deblur.jar" into any plugin directory or
subdirectory.
|
Description: |
Motion deblur reduces the blurring caused by objects in
quick motion during the image acquisition process. The
algorithm employed is based on Weiner deconvolution.
|
Usage: |
- Load any kind of supported image
-
Load "Motion Deblur" plugin: note that it will hook
to the active image.
-
Specify parameters to determine the point spread
function and the signal-to-noise ratio to
compensate. This can be done in three ways:
-
Using the line tool: drag a line on the
hooked image canvas (Shift/Angle only).
- Using the sliders.
-
Manually entering textual information in
textboxes. Max shift allowed is half of the
shortest image dimension, while max angle
is 180 degrees.
-
"Apply filter" will process the image and create a
new window containing the processed image.
(Optional: by ticking the "Show OTF" checkbox the
plugin will create another window showing the OTF
power spectrum).
The user can also generate a forensic report by pressing
the "Generate report" button. It will include the following
information:
- User, machine and current timestamp
-
Original and processed image filenames and MD5
hashes. Note that processed image will be saved as
a BMP file to prevent further degradation.
- Shift, Angle and SNR
- Bibliographic references
