type PtrOfLineSegmentDetector = Ptr<dyn LineSegmentDetector>;

Implementations

impl PtrOfLineSegmentDetector

pub fn as_raw_PtrOfLineSegmentDetector(&self) -> *const c_void

pub fn as_raw_mut_PtrOfLineSegmentDetector(&mut self) -> *mut c_void

Trait Implementations

impl AlgorithmTrait for PtrOfLineSegmentDetector

pub fn as_raw_Algorithm(&self) -> *const c_void

pub fn as_raw_mut_Algorithm(&mut self) -> *mut c_void

pub fn clear(&mut self) -> Result<()>

Clears the algorithm state

pub fn write(&self, fs: &mut FileStorage) -> Result<()>

Stores algorithm parameters in a file storage

pub fn write_with_name(&self, fs: &Ptr<FileStorage>, name: &str) -> Result<()>

simplified API for language bindings Stores algorithm parameters in a file storage

pub fn read(&mut self, fn_: &FileNode) -> Result<()>

Reads algorithm parameters from a file storage

pub fn empty(&self) -> Result<bool>

Returns true if the Algorithm is empty (e.g. in the very beginning or after unsuccessful read

pub fn save(&self, filename: &str) -> Result<()>

Saves the algorithm to a file. In order to make this method work, the derived class must implement Algorithm::write(FileStorage& fs).

pub fn get_default_name(&self) -> Result<String>

Returns the algorithm string identifier. This string is used as top level xml/yml node tag when the object is saved to a file or string.

impl LineSegmentDetector for PtrOfLineSegmentDetector

pub fn as_raw_LineSegmentDetector(&self) -> *const c_void

pub fn as_raw_mut_LineSegmentDetector(&mut self) -> *mut c_void

pub fn detect(
    &mut self,
    _image: &dyn ToInputArray,
    _lines: &mut dyn ToOutputArray,
    width: &mut dyn ToOutputArray,
    prec: &mut dyn ToOutputArray,
    nfa: &mut dyn ToOutputArray
) -> Result<()>

Finds lines in the input image.

pub fn draw_segments(
    &mut self,
    _image: &mut dyn ToInputOutputArray,
    lines: &dyn ToInputArray
) -> Result<()>

Draws the line segments on a given image.

pub fn compare_segments(
    &mut self,
    size: Size,
    lines1: &dyn ToInputArray,
    lines2: &dyn ToInputArray,
    _image: &mut dyn ToInputOutputArray
) -> Result<i32>

Draws two groups of lines in blue and red, counting the non overlapping (mismatching) pixels.
