Schärfungstechniken
Schärfungstechniken, often translated as sharpening techniques, refer to methods used to increase the perceived or actual sharpness of an image. In digital imaging, this primarily involves algorithms that enhance contrast along edges and fine details.
One common technique is unsharp masking (USM). This process works by creating a blurred version of the
Another approach is a high-pass filter. This filter isolates high-frequency details, which correspond to edges and
More advanced sharpening techniques may involve deconvolution algorithms, which attempt to reverse the blurring process itself,
