Class SyntheticSequenceGenerator

  • public class SyntheticSequenceGenerator
extends Algorithm
    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.

        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.
