Struct opencv::bgsegm::SyntheticSequenceGenerator

pub struct SyntheticSequenceGenerator { /* fields omitted */ }

Synthetic frame sequence generator for testing background subtraction algorithms.

It will generate the moving object on top of the background. It will apply some distortion to the background to make the test more complex.

Methods

impl SyntheticSequenceGenerator

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

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

impl SyntheticSequenceGenerator

pub fn new(
    background: &dyn ToInputArray,
    object: &dyn ToInputArray,
    amplitude: f64,
    wavelength: f64,
    wavespeed: f64,
    objspeed: f64
) -> Result<SyntheticSequenceGenerator>

Creates an instance of SyntheticSequenceGenerator.

Parameters

• background: Background image for object.
• object: Object image which will move slowly over the background.
• amplitude: Amplitude of wave distortion applied to background.
• wavelength: Length of waves in distortion applied to background.
• wavespeed: How fast waves will move.
• objspeed: How fast object will fly over background.

pub fn get_next_frame(
    &mut self,
    frame: &mut dyn ToOutputArray,
    gt_mask: &mut dyn ToOutputArray
) -> Result<()>

Obtain the next frame in the sequence.

Parameters

• frame: Output frame.
• gtMask: Output ground-truth (reference) segmentation mask object/background.

Trait Implementations

impl AlgorithmTrait for SyntheticSequenceGenerator

fn as_raw_Algorithm(&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_1(&self, fs: &PtrOfFileStorage, name: &str) -> Result<()>

simplified API for language bindings

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 Drop for SyntheticSequenceGenerator

fn drop(&mut self)

Executes the destructor for this type.
