Mutable methods for crate::cudaimgproc::CUDA_HoughLinesDetector

Required Methods§

Source

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

Provided Methods§

Source

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

Finds lines in a binary image using the classical Hough transform.

§Parameters
  • src: 8-bit, single-channel binary source image.
  • lines: Output vector of lines. Each line is represented by a two-element vector inline formula . inline formula is the distance from the coordinate origin inline formula (top-left corner of the image). inline formula is the line rotation angle in radians ( inline formula ).
  • stream: Stream for the asynchronous version.
§See also

HoughLines

§C++ default parameters
  • stream: Stream::Null()
Source

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

§Parameters
  • src: 8-bit, single-channel binary source image.
  • lines: Output vector of lines. Each line is represented by a two-element vector inline formula . inline formula is the distance from the coordinate origin inline formula (top-left corner of the image). inline formula is the line rotation angle in radians ( inline formula ).
  • stream: Stream for the asynchronous version.

HoughLines

§Note

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

  • stream: Stream::Null()
Source

fn download_results( &mut self, d_lines: &impl ToInputArray, h_lines: &mut impl ToOutputArray, h_votes: &mut impl ToOutputArray, stream: &mut impl StreamTrait, ) -> Result<()>

Downloads results from cuda::HoughLinesDetector::detect to host memory.

§Parameters
  • d_lines: Result of cuda::HoughLinesDetector::detect .
  • h_lines: Output host array.
  • h_votes: Optional output array for line’s votes.
  • stream: Stream for the asynchronous version.
§C++ default parameters
  • h_votes: noArray()
  • stream: Stream::Null()
Source

fn download_results_def( &mut self, d_lines: &impl ToInputArray, h_lines: &mut impl ToOutputArray, ) -> Result<()>

Downloads results from cuda::HoughLinesDetector::detect to host memory.

§Parameters
  • d_lines: Result of cuda::HoughLinesDetector::detect .
  • h_lines: Output host array.
  • h_votes: Optional output array for line’s votes.
  • stream: Stream for the asynchronous version.
§Note

This alternative version of CUDA_HoughLinesDetectorTrait::download_results function uses the following default values for its arguments:

  • h_votes: noArray()
  • stream: Stream::Null()
Source

fn set_rho(&mut self, rho: f32) -> Result<()>

Source

fn set_theta(&mut self, theta: f32) -> Result<()>

Source

fn set_threshold(&mut self, threshold: i32) -> Result<()>

Source

fn set_do_sort(&mut self, do_sort: bool) -> Result<()>

Source

fn set_max_lines(&mut self, max_lines: i32) -> 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.
