Sharpening Filter

Enhances the sharpness of a raster image by applying an unsharp mask filter algorithm.


Sharpening Filter enhances the sharpness of a raster image by applying an unsharpen masking filter algorithm. It supports three possible sharpening strength options. Both the input and output are GeoTIFF files.

In the unsharp masking algorithm, the sharp details are identified as the difference between the original image and its blurred version. These details are then scaled, and added back to the original image.

The source code is published as free software / open source (MIT License) here.
