Description

Builds an edge map using canny edge detection.

vsTCanny is a port of the VapourSynth plugin TCanny.


Requirements


Syntax and Parameters

vsTCanny (clip, float "sigmaY", float "sigmaU", float "sigmaV", float sigma_vY", float "sigma_vU", float "sigma_vV", float "t_h", float "t_l", int "mode", int "op", float "scale", int "y", int "u", int "v", int "opt")


clip   =
A clip to process. All planar formats are supported.


float  sigmaY = 1.5
float  sigmaU =
float  sigmaV =
Standard deviation of horizontal gaussian blur.
Must be positive value.
Setting to 0 disables gaussian blur.
Default: sigmaY = 1.5; sigmaU = sigmaV = sigmaY/2 for half resolution chroma and sigmaU = sigmaV = sigmaY for full resolution chroma.


float  sigma_vY = sigmaY
float  sigma_vU =
float  sigma_vV =
Standard deviation of vertical gaussian blur.
Must be positive value.
Setting to 0 disables gaussian blur.
Default: sigma_vY = sigmaY; sigma_vU = sigma_vV = sigma_vY/2 for half resolution chroma and sigma_vU = sigma_vV = sigma_vY for full resolution chroma.


float  t_h = 8.0
High gradient magnitude threshold for hysteresis.


float  t_l = 1.0
Low gradient magnitude threshold for hysteresis.
Must be lower than t_h.


int  mode = 0
Sets the output format:
  • -1 : Gaussian blur only.
  • 0 : Thresholded edge map (2^bitdepth-1 for edge, 0 for non-edge).
  • 1 : Gradient magnitude map.


int  op = 1
Sets the operator for edge detection:
  • 0 : The operator used in tritical's original filter.
  • 1 : The operator proposed by P. Zhou et al.
  • 2 : The Sobel operator.
  • 3 : The Scharr operator.
  • 4 : The Kroon operator.
  • 5 : The Kirsch operator.
  • 6 : he FDoG operator.


float  scale = 1.0
Multiplies the gradient.
This can be used to increase or decrease the intensity of edges in the output.
Must be greater than 0.0.


int  y = 3
int  u = 3
int  v = 3
Planes to process.
  • 1 : Return garbage.
  • 2 : Copy plane.
  • 3 : Process plane. Always process planes when the clip is RGB.


int  opt = -1
Sets which cpu optimizations to use.
  • -1 : Auto-detect.
  • 0 : Use C++ code.
  • 1 : Use SSE2 code.
  • 2 : Use AVX2 code.
  • 3 : Use AVX512 code.
