Implementations

impl PtrOfCUDA_NvidiaOpticalFlow_1_0

pub fn as_raw_mut_PtrOfCUDA_NvidiaOpticalFlow_1_0(&mut self) -> *mut c_void

Trait Implementations

impl AlgorithmTrait for PtrOfCUDA_NvidiaOpticalFlow_1_0

fn as_raw_Algorithm(&self) -> *const c_void

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

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

Clears the algorithm state

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

Reads algorithm parameters from 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 CUDA_NvidiaHWOpticalFlow for PtrOfCUDA_NvidiaOpticalFlow_1_0

fn as_raw_CUDA_NvidiaHWOpticalFlow(&self) -> *const c_void

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

fn calc(
    &mut self,
    input_image: &dyn ToInputArray,
    reference_image: &dyn ToInputArray,
    flow: &mut dyn ToInputOutputArray,
    stream: &mut Stream,
    hint: &dyn ToInputArray,
    cost: &mut dyn ToOutputArray
) -> Result<()>

Calculates Optical Flow using NVIDIA Optical Flow SDK.

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

Releases all buffers, contexts and device pointers.

fn get_grid_size(&self) -> Result<i32>

Returns grid size of output buffer as per the hardware's capability.

impl CUDA_NvidiaOpticalFlow_1_0 for PtrOfCUDA_NvidiaOpticalFlow_1_0

fn as_raw_CUDA_NvidiaOpticalFlow_1_0(&self) -> *const c_void

fn as_raw_mut_CUDA_NvidiaOpticalFlow_1_0(&mut self) -> *mut c_void

fn up_sampler(
    &mut self,
    flow: &dyn ToInputArray,
    width: i32,
    height: i32,
    grid_size: i32,
    upsampled_flow: &mut dyn ToInputOutputArray
) -> Result<()>

The NVIDIA optical flow hardware generates flow vectors at granularity gridSize, which can be queried via function getGridSize(). Upsampler() helper function converts the hardware-generated flow vectors to dense representation (1 flow vector for each pixel) using nearest neighbour upsampling method.
