Struct opencv::video::SparseOpticalFlow

pub struct SparseOpticalFlow { /* private fields */ }

Base interface for sparse optical flow algorithms.

Trait Implementations

impl AlgorithmTrait for SparseOpticalFlow

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

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

Clears the algorithm state

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

Reads algorithm parameters from a file storage

impl AlgorithmTraitConst for SparseOpticalFlow

fn as_raw_Algorithm(&self) -> *const c_void

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

Stores algorithm parameters in a file storage

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

Stores algorithm parameters in a file storage

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

@deprecated

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 SparseOpticalFlow

unsafe fn from_raw(ptr: *mut c_void) -> Self

Wrap the specified raw pointer

fn into_raw(self) -> *mut c_void

Return an the underlying raw pointer while consuming this wrapper.

fn as_raw(&self) -> *const c_void

Return the underlying raw pointer.

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

Return the underlying mutable raw pointer

impl Drop for SparseOpticalFlow

fn drop(&mut self)

Executes the destructor for this type.

impl From<SparseOpticalFlow> for Algorithm

fn from(s: SparseOpticalFlow) -> Self

Converts to this type from the input type.

impl SparseOpticalFlowTrait for SparseOpticalFlow

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

fn calc( &mut self, prev_img: &impl ToInputArray, next_img: &impl ToInputArray, prev_pts: &impl ToInputArray, next_pts: &mut impl ToInputOutputArray, status: &mut impl ToOutputArray, err: &mut impl ToOutputArray ) -> Result<()>

Calculates a sparse optical flow.

impl SparseOpticalFlowTraitConst for SparseOpticalFlow

fn as_raw_SparseOpticalFlow(&self) -> *const c_void
