Struct opencv::imgproc::LineSegmentDetector

pub struct LineSegmentDetector { /* private fields */ }

Line segment detector class

following the algorithm described at Rafael12 .

Note: Implementation has been removed from OpenCV version 3.4.6 to 3.4.15 and version 4.1.0 to 4.5.3 due original code license conflict. restored again after Computation of a NFA code published under the MIT license.

Trait Implementations

impl AlgorithmTrait for LineSegmentDetector

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

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

Clears the algorithm state

fn read(&mut self, fn_: &impl FileNodeTraitConst) -> Result<()>

Reads algorithm parameters from a file storage

impl AlgorithmTraitConst for LineSegmentDetector

fn as_raw_Algorithm(&self) -> *const c_void

fn write(&self, fs: &mut impl FileStorageTrait) -> Result<()>

Stores algorithm parameters in a file storage

fn write_1(&self, fs: &mut impl FileStorageTrait, name: &str) -> Result<()>

Stores algorithm parameters in a file storage

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

@deprecated

fn write_with_name_def(&self, fs: &Ptr<FileStorage>) -> Result<()>

👎Deprecated:

Note

Deprecated: ## Note This alternative version of AlgorithmTraitConst::write_with_name function uses the following default values for its arguments:

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

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

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).

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 Boxed for LineSegmentDetector

unsafe fn from_raw( ptr: <LineSegmentDetector as OpenCVFromExtern>::ExternReceive ) -> Self

Wrap the specified raw pointer

fn into_raw( self ) -> <LineSegmentDetector as OpenCVTypeExternContainer>::ExternSendMut

Return the underlying raw pointer while consuming this wrapper.

fn as_raw( &self ) -> <LineSegmentDetector as OpenCVTypeExternContainer>::ExternSend

Return the underlying raw pointer.

fn as_raw_mut( &mut self ) -> <LineSegmentDetector as OpenCVTypeExternContainer>::ExternSendMut

Return the underlying mutable raw pointer

impl Debug for LineSegmentDetector

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for LineSegmentDetector

fn drop(&mut self)

Executes the destructor for this type.

impl From<LineSegmentDetector> for Algorithm

fn from(s: LineSegmentDetector) -> Self

Converts to this type from the input type.

impl LineSegmentDetectorTrait for LineSegmentDetector

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

fn detect( &mut self, image: &impl ToInputArray, lines: &mut impl ToOutputArray, width: &mut impl ToOutputArray, prec: &mut impl ToOutputArray, nfa: &mut impl ToOutputArray ) -> Result<()>

Finds lines in the input image.

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

Finds lines in the input image.

fn draw_segments( &mut self, image: &mut impl ToInputOutputArray, lines: &impl ToInputArray ) -> Result<()>

Draws the line segments on a given image.

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

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

fn compare_segments_def( &mut self, size: Size, lines1: &impl ToInputArray, lines2: &impl ToInputArray ) -> Result<i32>

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