Introduction
For more information, please read the block description.
Block type: PROCESSING
This block enhances the sharpness of a satellite image by applying an Unsharp Masking Algorithm (UMA). It supports three possible sharpening strength options. Both the input and output are GeoTIFF files.
When applying UMA, 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.
Supported parameters
strength
: Strength of the image sharpening operation,light
,medium
andstrong
(default: medium).
