Mutable methods for crate::cudaimgproc::CUDA_CannyEdgeDetector

Required Methods§

Source

fn as_raw_mut_CUDA_CannyEdgeDetector(&mut self) -> *mut c_void

Provided Methods§

Source

fn detect( &mut self, image: &impl ToInputArray, edges: &mut impl ToOutputArray, stream: &mut impl StreamTrait, ) -> Result<()>

Finds edges in an image using the Canny86 algorithm.

§Parameters
  • image: Single-channel 8-bit input image.
  • edges: Output edge map. It has the same size and type as image.
  • stream: Stream for the asynchronous version.
§C++ default parameters
  • stream: Stream::Null()
Source

fn detect_def( &mut self, image: &impl ToInputArray, edges: &mut impl ToOutputArray, ) -> Result<()>

Finds edges in an image using the Canny86 algorithm.

§Parameters
  • image: Single-channel 8-bit input image.
  • edges: Output edge map. It has the same size and type as image.
  • stream: Stream for the asynchronous version.
§Note

This alternative version of CUDA_CannyEdgeDetectorTrait::detect function uses the following default values for its arguments:

  • stream: Stream::Null()
Source

fn detect_1( &mut self, dx: &impl ToInputArray, dy: &impl ToInputArray, edges: &mut impl ToOutputArray, stream: &mut impl StreamTrait, ) -> Result<()>

Finds edges in an image using the Canny86 algorithm.

§Parameters
  • image: Single-channel 8-bit input image.
  • edges: Output edge map. It has the same size and type as image.
  • stream: Stream for the asynchronous version.
§Overloaded parameters
  • dx: First derivative of image in the vertical direction. Support only CV_32S type.
  • dy: First derivative of image in the horizontal direction. Support only CV_32S type.
  • edges: Output edge map. It has the same size and type as image.
  • stream: Stream for the asynchronous version.
§C++ default parameters
  • stream: Stream::Null()
Source

Source

fn set_low_threshold(&mut self, low_thresh: f64) -> Result<()>

Source

fn set_high_threshold(&mut self, high_thresh: f64) -> Result<()>

Source

fn set_apperture_size(&mut self, apperture_size: i32) -> Result<()>

Source

fn set_l2_gradient(&mut self, l2gradient: bool) -> Result<()>

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
