Base class for background/foreground segmentation. :
The class is only used to define the common interface for the whole family of background/foreground segmentation algorithms.
|
pure virtual |
Computes a foreground mask.
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. |
|
pure virtual |
Computes a background image.
backgroundImage | The output background image. |
