Struct SyntheticSequenceGenerator

pub struct SyntheticSequenceGenerator { /* private fields */ }

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.

Implementations

impl SyntheticSequenceGenerator

pub fn new( background: &impl ToInputArray, object: &impl 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.

Trait Implementations

impl AlgorithmTrait for SyntheticSequenceGenerator

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

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

Clears the algorithm state

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

Reads algorithm parameters from a file storage

impl AlgorithmTraitConst for SyntheticSequenceGenerator

fn as_raw_Algorithm(&self) -> *const c_void

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

Stores algorithm parameters in a file storage

fn write_1(&self, fs: &mut impl FileStorageTrait, 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 AlgorithmTraitConst::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.

impl Boxed for SyntheticSequenceGenerator

unsafe fn from_raw( ptr: <SyntheticSequenceGenerator as OpenCVFromExtern>::ExternReceive, ) -> Self

Wrap the specified raw pointer

fn into_raw( self, ) -> <SyntheticSequenceGenerator as OpenCVTypeExternContainer>::ExternSendMut

Return the underlying raw pointer while consuming this wrapper.

fn as_raw( &self, ) -> <SyntheticSequenceGenerator as OpenCVTypeExternContainer>::ExternSend

Return the underlying raw pointer.

fn as_raw_mut( &mut self, ) -> <SyntheticSequenceGenerator as OpenCVTypeExternContainer>::ExternSendMut

Return the underlying mutable raw pointer

impl Debug for SyntheticSequenceGenerator

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for SyntheticSequenceGenerator

fn drop(&mut self)

Executes the destructor for this type.

impl From<SyntheticSequenceGenerator> for Algorithm

fn from(s: SyntheticSequenceGenerator) -> Self

Converts to this type from the input type.

impl SyntheticSequenceGeneratorTrait for SyntheticSequenceGenerator

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

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

Obtain the next frame in the sequence.
