bob.ip.FaceEyesNorm

class bob.ip.FaceEyesNorm((object)self, (float)eyes_distance, (int)crop_height, (int)crop_width, (float)crop_eyecenter_offset_h, (float)crop_eyecenter_offset_w) → None :

Bases: Boost.Python.instance

Objects of this class, after configuration, can extract and normalize faces, given their eye center coordinates.

Constructs a FaceEyeNorm object.

__init__( (object)self, (int)crop_height, (int)crop_width, (int)re_y, (int)re_x, (int)le_y, (int)le_x) -> None :

Creates a FaceEyesNorm class that will put the eyes to the given locations and crop the image to the desired size.

__init__( (object)self, (FaceEyesNorm)other) -> None

__init__((object)self, (float)eyes_distance, (int)crop_height, (int)crop_width, (float)crop_eyecenter_offset_h, (float)crop_eyecenter_offset_w) → None :

Constructs a FaceEyeNorm object.

__init__( (object)self, (int)crop_height, (int)crop_width, (int)re_y, (int)re_x, (int)le_y, (int)le_x) -> None :

Creates a FaceEyesNorm class that will put the eyes to the given locations and crop the image to the desired size.

__init__( (object)self, (FaceEyesNorm)other) -> None

Methods

__init__((object)self, (float)eyes_distance, …)

Constructs a FaceEyeNorm object.

Attributes

crop_height	Height of the cropping area after the geometric normalization.
crop_offset_h	y-coordinate of the point in the cropping area which is the middle of the segment defined by the eyes after the geometric normalization.
crop_offset_w	x-coordinate of the point in the cropping area which is the middle of the segment defined by the eyes after the geometric normalization.
crop_width	Width of the cropping area after the geometric normalization.
eyes_distance	Expected distance between the eyes after the geometric normalization.
last_angle	The angle value (in degrees) used by the rotation involved in the last call of the operator ()
last_scale	The scaling factor used by the scaling involved in the last call of the operator ()

__call__((FaceEyesNorm)self, (object)input, (object)output, (float)re_y, (float)re_x, (float)le_y, (float)le_x) → None :

Extracts a face given the coordinates of the left (le_y, le_x) and right (re_y, re_x) eye centers. Please note that the horizontal position le_x of the left eye is usually larger than the position re_x of the right eye.

__call__( (FaceEyesNorm)self, (object)input, (float)re_y, (float)re_x, (float)le_y, (float)le_x) -> object :

Extracts a face given the coordinates of the left (le_y, le_x) and right (re_y, re_x) eye centers. Please note that the horizontal position le_x of the left eye is usually larger than the position re_x of the right eye. The output is allocated and returned.

__call__( (FaceEyesNorm)self, (object)input, (object)input_mask, (object)output, (object)output_mask, (float)re_y, (float)re_x, (float)le_y, (float)le_x) -> None :

Extracts a face given the coordinates of the left (le_y, le_x) and right (re_y, re_x) eye centers, taking mask into account.
