A Sobel edge detection filter.
- aSobel (clip, int "thresh", 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.
- Range: 0 to 255
- int thresh = 128
- int chroma = 1
- 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 = 1
Examples
aSobel with default values:
AviSource("blah.avi") aSobel(thresh=128, chroma=1)
