Mutable methods for crate::ximgproc::EdgeDrawing

Required Methods§

Source

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

Provided Methods§

Source

fn set_params(&mut self, val: EdgeDrawing_Params)

Source

fn detect_edges(&mut self, src: &impl ToInputArray) -> Result<()>

Detects edges in a grayscale image and prepares them to detect lines and ellipses.

§Parameters
  • src: 8-bit, single-channel, grayscale input image.
Source

fn get_edge_image(&mut self, dst: &mut impl ToOutputArray) -> Result<()>

returns Edge Image prepared by detectEdges() function.

§Parameters
  • dst: returns 8-bit, single-channel output image.
Source

fn get_gradient_image(&mut self, dst: &mut impl ToOutputArray) -> Result<()>

returns Gradient Image prepared by detectEdges() function.

§Parameters
  • dst: returns 16-bit, single-channel output image.
Source

fn get_segments(&mut self) -> Result<Vector<Vector<Point>>>

Returns std::vector<std::vector> of detected edge segments, see detectEdges()

Source

fn detect_lines(&mut self, lines: &mut impl ToOutputArray) -> Result<()>

Detects lines.

§Parameters
  • lines: output Vec<4f> contains the start point and the end point of detected lines.

Note: you should call detectEdges() before calling this function.

Source

fn detect_ellipses(&mut self, ellipses: &mut impl ToOutputArray) -> Result<()>

Detects circles and ellipses.

§Parameters
  • ellipses: output Vec<6d> contains center point and perimeter for circles, center point, axes and angle for ellipses.

Note: you should call detectEdges() before calling this function.

Source

fn set_params_1(&mut self, parameters: EdgeDrawing_Params) -> Result<()>

sets parameters.

this function is meant to be used for parameter setting in other languages than c++ like python.

§Parameters
  • parameters: Parameters of the algorithm

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.
