/aWarpSharp2

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.

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.

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.

depth int = 16

Range: -128 to 127

Strength of the final warping. Negative values result in warping in oppositedirection.

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
