pub fn as_raw_mut_PtrOfBackgroundSubtractorCNT(&mut self) -> *mut c_void

Trait Implementations

impl AlgorithmTrait for PtrOfBackgroundSubtractorCNT

pub fn as_raw_Algorithm(&self) -> *const c_void

pub fn as_raw_mut_Algorithm(&mut self) -> *mut c_void

pub fn clear(&mut self) -> Result<()>

Clears the algorithm state

pub fn write(&self, fs: &mut FileStorage) -> Result<()>

Stores algorithm parameters in a file storage

pub fn write_with_name(&self, fs: &Ptr<FileStorage>, name: &str) -> Result<()>

simplified API for language bindings Stores algorithm parameters in a file storage

pub fn read(&mut self, fn_: &FileNode) -> Result<()>

Reads algorithm parameters from a file storage

pub fn empty(&self) -> Result<bool>

Returns true if the Algorithm is empty (e.g. in the very beginning or after unsuccessful read

pub fn save(&self, filename: &str) -> Result<()>

Saves the algorithm to a file. In order to make this method work, the derived class must implement Algorithm::write(FileStorage& fs).

pub fn get_default_name(&self) -> Result<String>

Returns the algorithm string identifier. This string is used as top level xml/yml node tag when the object is saved to a file or string.

impl BackgroundSubtractor for PtrOfBackgroundSubtractorCNT

pub fn as_raw_BackgroundSubtractor(&self) -> *const c_void

pub fn as_raw_mut_BackgroundSubtractor(&mut self) -> *mut c_void

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

Computes a foreground mask.

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

Computes a background image.

impl BackgroundSubtractorCNT for PtrOfBackgroundSubtractorCNT

pub fn as_raw_BackgroundSubtractorCNT(&self) -> *const c_void

pub fn as_raw_mut_BackgroundSubtractorCNT(&mut self) -> *mut c_void

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

C++ default parameters

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

pub fn get_min_pixel_stability(&self) -> Result<i32>

Returns number of frames with same pixel color to consider stable.

pub fn set_min_pixel_stability(&mut self, value: i32) -> Result<()>

Sets the number of frames with same pixel color to consider stable.

pub fn get_max_pixel_stability(&self) -> Result<i32>

Returns maximum allowed credit for a pixel in history.

pub fn set_max_pixel_stability(&mut self, value: i32) -> Result<()>

Sets the maximum allowed credit for a pixel in history.

pub fn get_use_history(&self) -> Result<bool>

Returns if we're giving a pixel credit for being stable for a long time.

pub fn set_use_history(&mut self, value: bool) -> Result<()>

Sets if we're giving a pixel credit for being stable for a long time.

pub fn get_is_parallel(&self) -> Result<bool>

Returns if we're parallelizing the algorithm.

pub fn set_is_parallel(&mut self, value: bool) -> Result<()>

Sets if we're parallelizing the algorithm.
