Struct opencv::face::BIF

pub struct BIF { /* private fields */ }

Implementation of bio-inspired features (BIF) from the paper: Guo, Guodong, et al. “Human age estimation using bio-inspired features.” Computer Vision and Pattern Recognition, 2009. CVPR 2009.

Implementations

impl BIF

pub fn create(num_bands: i32, num_rotations: i32) -> Result<Ptr<BIF>>

Parameters

• num_bands: The number of filter bands (<=8) used for computing BIF.
• num_rotations: The number of image rotations for computing BIF.

Returns

Object for computing BIF.

C++ default parameters

• num_bands: 8
• num_rotations: 12

pub fn create_def() -> Result<Ptr<BIF>>

Parameters

• num_bands: The number of filter bands (<=8) used for computing BIF.
• num_rotations: The number of image rotations for computing BIF.

Returns

Object for computing BIF.

Note

This alternative version of BIF::create function uses the following default values for its arguments:

• num_bands: 8
• num_rotations: 12

Trait Implementations

impl AlgorithmTrait for BIF

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

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

Clears the algorithm state

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

Reads algorithm parameters from a file storage

impl AlgorithmTraitConst for BIF

fn as_raw_Algorithm(&self) -> *const c_void

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

Stores algorithm parameters in a file storage

fn write_1(&self, fs: &mut FileStorage, name: &str) -> Result<()>

Stores algorithm parameters in a file storage

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

@deprecated

fn write_with_name_def(&self, fs: &Ptr<FileStorage>) -> Result<()>

👎Deprecated:

Note

Deprecated: ## Note This alternative version of AlgorithmTraitConst::write_with_name function uses the following default values for its arguments:

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

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

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).

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 BIFTrait for BIF

fn as_raw_mut_BIF(&mut self) -> *mut c_void

impl BIFTraitConst for BIF

fn as_raw_BIF(&self) -> *const c_void

fn get_num_bands(&self) -> Result<i32>

Returns

fn get_num_rotations(&self) -> Result<i32>

Returns

fn compute( &self, image: &impl ToInputArray, features: &mut impl ToOutputArray ) -> Result<()>

Computes features sby input image.

impl Boxed for BIF

unsafe fn from_raw(ptr: *mut c_void) -> Self

Wrap the specified raw pointer

fn into_raw(self) -> *mut c_void

Return an the underlying raw pointer while consuming this wrapper.

fn as_raw(&self) -> *const c_void

Return the underlying raw pointer.

fn as_raw_mut(&mut self) -> *mut c_void

Return the underlying mutable raw pointer

impl Debug for BIF

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for BIF

fn drop(&mut self)

Executes the destructor for this type.

impl From<BIF> for Algorithm

fn from(s: BIF) -> Self

Converts to this type from the input type.
