Ptr<BackgroundSubtractorGMG> cv::bgsegm::createBackgroundSubtractorGMG | ( | int | initializationFrames = 120 , |
double | decisionThreshold = 0.8 |
||
) |
Creates a GMG Background Subtractor.
initializationFrames | number of frames used to initialize the background models. |
decisionThreshold | Threshold value, above which it is marked foreground, else background. |
Ptr<BackgroundSubtractorMOG> cv::bgsegm::createBackgroundSubtractorMOG | ( | int | history = 200 , |
int | nmixtures = 5 , |
||
double | backgroundRatio = 0.7 , |
||
double | noiseSigma = 0 |
||
) |
Creates mixture-of-gaussian background subtractor.
history | Length of the history. |
nmixtures | Number of Gaussian mixtures. |
backgroundRatio | Background ratio. |
noiseSigma | Noise strength (standard deviation of the brightness or each color channel). 0 means some automatic value. |
