## Detailed Description

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.

## Constructor & Destructor Documentation

## § SyntheticSequenceGenerator()

cv::bgsegm::SyntheticSequenceGenerator::SyntheticSequenceGenerator | ( | InputArray | background,
|  | InputArray | object,
|  | double | amplitude,
|  | double | wavelength,
|  | double | wavespeed,
|  | double | objspeed
| ) |  |

Python:
| <bgsegm_SyntheticSequenceGenerator object> | = | cv.bgsegm_SyntheticSequenceGenerator( | background, object, amplitude, wavelength, wavespeed, objspeed | )

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.

## Member Function Documentation

## § getNextFrame()

void cv::bgsegm::SyntheticSequenceGenerator::getNextFrame | ( | OutputArray | frame,
|  | OutputArray | gtMask
| ) |  |

Python:
| frame, gtMask | = | cv.bgsegm_SyntheticSequenceGenerator.getNextFrame( | [, frame[, gtMask]] | )

Obtain the next frame in the sequence.

Parameters

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