Back to aWarpSharp2.
Description
The same as aWarp(aSobel().aBlur()) but a bit faster.
Syntax and Parameters
- aWarpSharp2(int "thresh", int "blur", int "type", int "depth", int "chroma")
- thresh int = 128
- Range: 0 to 255
- Saturation limit for edge detection. Reduce for less aggressive sharpening.
- Range: 0 to 255
- blur int = 2 for type 0, 3 for type 1
- Range: 0 to 100
- Number of blur passes over edge mask.
- Less passes increase sharpening effect, but can produce major artifacts with high depth and thresh.
- You can use values higher than 100, but probably won't see any difference.
- Chroma is processed with (blur+1)/2 passes.
- Number of blur passes over edge mask.
- Range: 0 to 100
- type int = 0
- Type of blur:
- 0 : radius 6 blur.
- 1 : radius 2 blur, requires around 8x more passes than type 0 for the same effect (will be just 2.5x slower), but produce better quality.
- Type of blur:
- depth int = 16
- Range: -128 to 127
- Strength of the final warping. Negative values result in warping in oppositedirection.
- Range: -128 to 127
- chroma int = 4
- Processing mode for chroma planes (U and V):
- 0 : fill with zeroes
- 1 : don't care, default for aSobel and aBlur
- 2 : copy
- 3 : process
- 4 : guide by luma - default for aWarpSharp, aWarp, and aWarp4 only
- 5 : same as 3, but don't process luma
- 6 : same as 4, but don't process luma
- Processing mode for chroma planes (U and V):
