| Sharpen |
|
The Sharpen filter enhances edges using a simple algorithm. This is very fast to compute but can produce artificially over-sharp or over-noisy images if not used carefully. The Sharpen Filter uses a simple three square convolution to enhance edges. The value at the center is +2.0 and the value at the edges is -0.125. |
