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.
