Sharpening Filter

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


Description

A processing block that enhances the sharpness of a satellite image by applying an Unsharp Masking Algorithm (UMA).

See this block on the marketplace.

How it works

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.

ParameterOverview
strengthstring / required
Strength of the image sharpening operation:
  • light
  • medium
  • strong
The default value is medium.
