Package org.opencv.bgsegm
Class BackgroundSubtractorGSOC
java.lang.Object
org.opencv.core.Algorithm
org.opencv.video.BackgroundSubtractor
org.opencv.bgsegm.BackgroundSubtractorGSOC
Implementation of the different yet better algorithm which is called GSOC, as it was implemented during GSOC and was not originated from any paper.
This algorithm demonstrates better performance on CDNET 2014 dataset compared to other algorithms in OpenCV.

apply
Description copied from class:BackgroundSubtractor
Computes a foreground mask.- Overrides:
apply
in classBackgroundSubtractor
- Parameters:
image
- Next video frame.fgmask
- The output foreground mask as an 8-bit binary image.learningRate
- The value between 0 and 1 that indicates how fast the background model is learnt. Negative parameter value makes the algorithm to use some automatically chosen learning rate. 0 means that the background model is not updated at all, 1 means that the background model is completely reinitialized from the last frame.
