Constructor & Destructor Documentation

◆ NormalizationLayerInfo()

NormalizationLayerInfo ( NormType  type,
uint32_t  norm_size = 5,
float  alpha = 0.0001f,
float  beta = 0.5f,
float  kappa = 1.f,
bool  is_scaled = true 
)
inline

Default Constructor.

Parameters
[in]typeThe normalization type. Can be NormType::IN_MAP_1D, NormType::IN_MAP_2D or NormType::CROSS_MAP
[in]norm_sizeThe normalization size is the number of elements to normalize across. Defaults to 5.
[in]alpha(Optional) Alpha parameter used by normalization equation. Defaults to 0.0001.
[in]beta(Optional) Beta parameter used by normalization equation. Defaults to 0.5.
[in]kappa(Optional) Kappa parameter used by [Krichevksy 2012] Across Channel Local Brightness Normalization equation.
[in]is_scaled(Optional) Boolean that specifies if alpha will be scaled by the normalization size or not. Should be false to follow [Krichevksy 2012].

◆ alpha()

float alpha ( ) const
inline

Get the alpha value.

◆ beta()

float beta ( ) const
inline

◆ is_cross_map()

bool is_cross_map ( ) const
inline

Check if normalization is cross map.

Normalization applied cross maps.

◆ is_in_map()

bool is_in_map ( ) const
inline

Check if normalization is not cross map.

1703  }
bool is_cross_map() const
Check if normalization is cross map.
Definition: Types.h:1695

◆ is_scaled()

bool is_scaled ( ) const
inline

Get the is_scaled value.

Definition at line 1690 of file Types.h.

1691  {
1692  return _is_scaled;
1693  }

◆ kappa()

float kappa ( ) const
inline

◆ norm_size()

uint32_t norm_size ( ) const
inline

◆ scale_coeff()

float scale_coeff ( ) const
inline

Return the scaling factor of the normalization function.

If is_scaled is set to false then [Krichevksy 2012] normalization scaling is performed, where alpha is returned plainly, else alpha is scaled by the total number of elements used for the normalization.

Returns
The normalization scaling factor.
