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.

Required methods

`pub fn as_raw_BackgroundSubtractor(&self) -> *const c_void`[src]

`pub fn as_raw_mut_BackgroundSubtractor(&mut self) -> *mut c_void`[src]

Provided methods

`pub fn apply( &mut self, image: &dyn ToInputArray, fgmask: &mut dyn ToOutputArray, learning_rate: f64 ) -> Result<()>`[src]

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

`pub fn get_background_image( &self, background_image: &mut dyn ToOutputArray ) -> Result<()>`[src]

Computes a background image.

Parameters

backgroundImage: The output background image.

Note: Sometimes the background image can be very blurry, as it contain the average background statistics.
