Adobe Photoshop is a widely used software for image editing and manipulation, including sharpening.

The Radius parameter controls the amount of sharpening applied to the image, with higher values resulting in more sharpening.

The Unsharp Mask technique involves applying a sharpening filter directly to the original image, without creating a new layer.

The Threshold parameter determines the minimum difference in pixel values required for sharpening to be applied, helping to prevent over-sharpening.

GIMP is a free and open-source software that provides similar image editing and manipulation capabilities as Adobe Photoshop, including sharpening.

The Amount parameter controls the amount of sharpening applied to the image, with higher values resulting in more sharpening.

The High Pass Filter technique involves applying a sharpening filter to a duplicate layer, then blending it with the original image to enhance the edges.

The Gaussian Blur filter is used to reduce noise in an image, which can help to improve the effectiveness of sharpening tools.
