FUNCTIONbgsegm_createBackgroundSubtractorGSOC

RETURN TYPEbgsegm_BackgroundSubtractorGSOC | null

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Creates an instance of BackgroundSubtractorGSOC algorithm.

Implementation of the different yet better algorithm which is called GSOC, as it was implemented during GSOC and was not originated from any paper.

mc: Whether to use camera motion compensation.
nSamples: Number of samples to maintain at each point of the frame.
replaceRate: Probability of replacing the old sample - how fast the model will update itself.
propagationRate: Probability of propagating to neighbors.
hitsThreshold: How many positives the sample must get before it will be considered as a possible replacement.
alpha: Scale coefficient for threshold.
beta: Bias coefficient for threshold.
blinkingSupressionDecay: Blinking supression decay factor.
blinkingSupressionMultiplier: Blinking supression multiplier.
noiseRemovalThresholdFacBG: Strength of the noise removal for background points.
noiseRemovalThresholdFacFG: Strength of the noise removal for foreground points.

Returns
