aWarpSharp2 performs edge detection, blurring, and warping, all in one.
[edit] Syntax and Parameters
- aWarpSharp2 (clip, int "thresh", int "blur", int "type", int "depth", int "chroma")
- clip =
- Input clip.
- clip =
- int thresh = 128
- Saturation limit for edge detection; no pixel in the edge mask will have a value greater than thresh. Reduce for less aggressive sharpening.
- Range: 0 to 255
- int thresh = 128
- int blur = 2
- Number of blur passes over edge mask. Less passes increase sharpening effect, but can produce major artifacts with high depth and thresh values.
- You can use values higher than 100, but probably won't see any difference. Chroma is processed with
(blur+1)/2passes.
- 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 values.
- int blur = 2
- Note: Unless blur is specifically set, it will default to 3 if type=1.
- int type = 0
- Type of blur:
- 0 : radius 6 blur (some kind of 13x13 average).
- 1 : radius 2 blur (some kind of 5x5 average), requires around 8x more passes than type=0 for the same effect (will be 2.5x slower), but will produce better quality.
- Type of blur:
- int type = 0
- int depth = 16
- Strength of the final warping. Negative values result in warping in opposite direction, i.e. will blur the image instead of sharpening.
- Range: -128 to 127
- Note: Chroma channels are internally processed with
depth/2.
- int depth = 16
- int chroma = 4
- Processing mode for the chroma channels (U and V):
- 0 : fill with 0x80(128), output is grayscale.
- 1 : don't care - chroma will be trashed.
- 2 : copy chroma channels from the input clip.
- 3 : process chroma; create an edge mask from each chroma channel and use those to warp each chroma channel individually.
- 4 : process chroma; use the edge mask from the luma to warp the chroma channels.
- 5 : same as 3, but don't process luma.
- 6 : same as 4, but don't process luma.
- Luma plane (Y) is always processed, except for mode 5 and 6 which simply copy the luma channel from the input clip.
- Processing mode for the chroma channels (U and V):
- int chroma = 4
[edit] Examples
aWarpSharp2 with default values:
AviSource("Blah.avi") aWarpSharp2(thresh=128, blur=2, type=0, depth=16, chroma=4)
#The same as aWarp(aSobel().aBlur(blur=2, type=0), depth=16) but a bit faster.
Guide chroma channels with luma edge mask but only process chroma (luma channel will be copied from the input clip).
aWarpSharp2(thresh=128, blur=2, type=0, depth=16, chroma=6)
#Identical to MergeChroma(last, aWarpSharp2()) but faster and more memory efficient.
Process chroma channels with their own independent edge mask and copy luma channel from the input clip.
aWarpSharp2(thresh=128, blur=2, type=0, depth=16, chroma=5)
#Identical to MergeChroma(last, aWarpSharp2(chroma=3)) but faster and more memory efficient.
Only process the luma channel and copy chroma channels from the input clip.
aWarpSharp2(thresh=128, blur=2, type=0, depth=16, chroma=2)
#Identical to MergeLuma(last, aWarpSharp2()) but faster and more memory efficient.
