Protected Member Functions inherited from cv::Algorithm | |
void | writeFormat (FileStorage &fs) const |
The class discriminates between foreground and background pixels by building and maintaining a model of the background.
Any pixel which does not fit this model is then deemed to be foreground. The class implements algorithm described in [116] .
