Struct opencv::cudaoptflow::CUDA_DensePyrLKOpticalFlow

pub struct CUDA_DensePyrLKOpticalFlow { /* private fields */ }

Class used for calculating a dense optical flow.

The class can calculate an optical flow for a dense optical flow using the iterative Lucas-Kanade method with pyramids.

Implementations

impl CUDA_DensePyrLKOpticalFlow

pub fn create( win_size: Size, max_level: i32, iters: i32, use_initial_flow: bool ) -> Result<Ptr<CUDA_DensePyrLKOpticalFlow>>

C++ default parameters

• win_size: Size(13,13)
• max_level: 3
• iters: 30
• use_initial_flow: false

pub fn create_def() -> Result<Ptr<CUDA_DensePyrLKOpticalFlow>>

Note

This alternative version of [create] function uses the following default values for its arguments:

• win_size: Size(13,13)
• max_level: 3
• iters: 30
• use_initial_flow: false

Trait Implementations

impl AlgorithmTrait for CUDA_DensePyrLKOpticalFlow

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 CUDA_DensePyrLKOpticalFlow

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

👎Deprecated:

Note

Deprecated: ## Note This alternative version of [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.
