Sharpening Filter

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.

Parameter	Overview
`strength`	string / required Strength of the image sharpening operation: `light` `medium` `strong` The default value is `medium`.
