RETURN TYPEOwned native handle

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Native object: release it with using or delete(). Factories can return null; check before calling methods. Inherits Algorithm.

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.

Constructors and members

static create

Create an owned face_BIF instance with the supplied configuration.

create(num_bands: number, num_rotations: number): face_BIF | null;

3 available overloads

create(): face_BIF | null;

create(num_bands: number): face_BIF | null;

create(num_bands: number, num_rotations: number): face_BIF | null;

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.

Upstream declaration ↗

clone

Create another handle to the same native object. This retains the object without copying its pixels or algorithm state; dispose both handles separately.

clone(): this;

Returns

The this result.

getNumBands

Return the num bands configured on this face_BIF object.

getNumBands(): number;

Returns

The number of filter bands used for computing BIF.

Upstream declaration ↗

getNumRotations

Return the num rotations configured on this face_BIF object.

getNumRotations(): number;

Returns

The number of image rotations.

Upstream declaration ↗

compute

Computes features sby input image.

compute(image: Mat, features: Mat): void;

image

Input image (CV_32FC1).

features

Output destination, filled by the native operation. Feature vector (CV_32FC1).
