Description
TCannyMod is a Canny edge detection filter. It's based on tcanny written by Kevin Stone (a.k.a. tritical) but rewritten from scratch exclusively for AviSynth 2.6.
Requirements
Syntax and Parameters
TCannyMod
Builds an edge map using Canny edge detection.
- TCannyMod (clip, int "mode", float "sigma", float "t_h", float "t_l", bool "sobel", int "chroma")
- clip =
- Input clip; only planar formats are supported.
- clip =
- int mode = 0
- Sets the output format:
- int mode = 0
- 0 : thresholded edge map (255 for edge, 0 for non-edge)
- 1 : gradient magnitude map.
- 2 : edge pixel only gradient direction map (non-edge pixels set to 0)
- 3 : gradient direction map
- Gradient direction are normalized to 1, 3, 7 and 15.
- 1 = horizontal
- 3 = 45' up
- 7 = vertical
- 15 = 45' down
- 4 : Gaussian blurred frame.
- float sigma = 1.5
- Standard deviation of Gaussian blur. 0 means no blurring before edge detection.
- (0 <= sigma <= 2.83, default = 1.5)
- float sigma = 1.5
- float t_h = 8.0
- float t_l = 1.0
- High and low gradient magnitude threshold for hysteresis; t_h must be greater than t_l.
- float t_h = 8.0
- bool sobel = false
- If set to true, edge detection will use a Sobel operator instead of [1, 0, -1].
- bool sobel = false
- int chroma = 0
- Chroma processing:
- int chroma = 0
- 0 : do not process
- 1 : process
- 2 : copy from input clip.
- 3 : fill with 0x80(128), output is grayscale.
GBlur
Gaussian blur filter. Just an alias for TCannyMod(mode=4).
- GBlur (clip, float "sigma", int "chroma")
- clip =
- Input clip; only planar formats are supported.
- clip =
- float sigma = 0.5
- Standard deviation of Gaussian blur. 0 means no blurring before edge detection.
- (0 <= sigma <= 2.83, default = 0.5)
- float sigma = 0.5
- int chroma = 1
- Chroma processing:
- int chroma = 1
- 0 : do not process
- 1 : process
- 2 : copy from input clip.
- 3 : fill with 0x80(128), output is grayscale.
Examples
TCannyMod with default settings:
AviSource("blah.avi") TCannyMod (mode=0, sigma=1.5, t_h=8.0, t_l=1.0, sobel=false, chroma=0)
GBlur with default settings:
AviSource("blah.avi") GBlur (sigma=0.5, chroma=1)
Changelog
