Trait Implementations

impl AlgorithmTrait for PtrOfSparseOpticalFlow

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 PtrOfSparseOpticalFlow

fn as_raw_Algorithm(&self) -> *const c_void

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

Stores algorithm parameters in a file storage

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

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

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 SparseOpticalFlow for PtrOfSparseOpticalFlow

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

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

Calculates a sparse optical flow.
