bob.ip.GradientMaps¶

class bob.ip.GradientMaps((object)self, (int)height, (int)width[, (GradientMagnitudeType)mag_type=bob.ip._ip.GradientMagnitudeType.Magnitude]) → None :¶

Bases: Boost.Python.instance

Objects of this class, after configuration, can extract gradient magnitude and orientation maps.

Constructs a new Gradient maps extractor.

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

__init__((object)self, (int)height, (int)width[, (GradientMagnitudeType)mag_type=bob.ip._ip.GradientMagnitudeType.Magnitude]) → None :¶

Constructs a new Gradient maps extractor.

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

Methods

`__init__`((object)self, (int)height, …)	Constructs a new Gradient maps extractor.
`forward`((GradientMaps)self, (object)input, …)	Extract the gradient magnitude and orientation maps.
`forward_`((GradientMaps)self, (object)input, …)	Extract the gradient magnitude and orientation maps.
`resize`((GradientMaps)self, (int)height, …)

Attributes

`height`	Height of the input image to process.
`magnitude_type`	Type of the magnitude to use for the returned maps.
`width`	Width of the input image to process.

__call__((GradientMaps)self, (object)input, (object)magnitude, (object)orientation) → None :¶

Extract the gradient magnitude and orientation maps.

__call__( (GradientMaps)self, (object)input) -> tuple :: Extract the gradient magnitude and orientation maps.

forward((GradientMaps)self, (object)input, (object)magnitude, (object)orientation) → None :¶

Extract the gradient magnitude and orientation maps.

forward( (GradientMaps)self, (object)input) -> tuple :: Extract the gradient magnitude and orientation maps.

forward_((GradientMaps)self, (object)input, (object)magnitude, (object)orientation) → None :¶

Extract the gradient magnitude and orientation maps. This variant does not check the inputs.

forward_( (GradientMaps)self, (object)input) -> tuple :: Extract the gradient magnitude and orientation maps. This variant does not check the inputs.

height¶: Height of the input image to process.

magnitude_type¶: Type of the magnitude to use for the returned maps.

resize((GradientMaps)self, (int)height, (int)width) → None¶

width¶: Width of the input image to process.
