Source
pub fn create_canny_edge_detector(
    low_thresh: f64,

Expand description

Creates implementation for cuda::CannyEdgeDetector .

§Parameters

  • low_thresh: First threshold for the hysteresis procedure.
  • high_thresh: Second threshold for the hysteresis procedure.
  • apperture_size: Aperture size for the Sobel operator.
  • L2gradient: Flag indicating whether a more accurate inline formula norm inline formula should be used to compute the image gradient magnitude ( L2gradient=true ), or a faster default inline formula norm inline formula is enough ( L2gradient=false ).

§C++ default parameters

  • apperture_size: 3
  • l2gradient: false
