Required Methods

Provided Methods

Computes a foreground mask.

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.
C++ default parameters
  • learning_rate: -1
