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,

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

Creates an instance of SyntheticSequenceGenerator.

Parameters
backgroundBackground image for object.
objectObject image which will move slowly over the background.
