Final answer:
Unsharp Masking is a sharpening method that allows adjusting the Amount, Radius, and Threshold to enhance image detail and edges.
Step-by-step explanation:
The sharpening method that allows adjusting the Amount, Radius, and Threshold is called Unsharp Masking. Unsharp Masking is a popular sharpening technique in digital image processing. It works by creating a blurred version of the image and then subtracting it from the original image to enhance the edges and details.
When applying Unsharp Masking, the Amount determines the strength of the sharpening effect, the Radius controls the width of the sharpening halo around edges, and the Threshold sets the minimum difference in pixel intensity required for an area to be considered an edge. By adjusting these parameters, you can fine-tune the sharpening process to achieve the desired result.
