|
During image processing operations such as scanning and scaling,
|
|
images tend to get blurry.
|
|
|
|
The blurred impression of these images is due to the fact that image
|
|
pixels are averaged with their neighbors. Blurred images don't have
|
|
sharp boundaries and look as though they have been taken with an
|
|
unfocussed camera.
|
|
|
|
Refocus is a GIMP plug-in to "refocus" the image, using a technique
|
|
called FIR Wiener filtering. The traditional technique for sharpening
|
|
images is to use unsharp masking. Refocus generally produces better
|
|
results than unsharp masking.
|
|
|
|
The plugin can be found under "Filters > Enhance > Refocus"
