Schärfefilterung
Schärfefilterung, often translated as sharpening filter or unsharp masking, is a digital image processing technique used to enhance the perceived detail and sharpness of an image. It works by increasing the contrast along edges within an image, making them appear more defined. The process typically involves creating a blurred version of the original image, then subtracting this blurred version from the original. This results in an image where only the edges with significant contrast are amplified, while smoother areas remain relatively unchanged.
The effectiveness of schärfefilterung is controlled by several parameters. The radius determines the width of the
While schärfefilterung can significantly improve the visual clarity of an image, overuse can lead to undesirable
