Member Function Documentation

ApplyDistort()

SimpleDatum MyCaffe.data.ImageTransforms< T >.ApplyDistort	(	SimpleDatum	sd,
		DistortionParameter	p
	)

The ApplyDistort method applies the distortion policy to the simple datum.

Parameters

sd	Specifies the SimpleDatum to distort.
p	Specifies the distortion parameters that define the distortion policy.

Returns

The distorted SimpleDatum is returned.

Definition at line 402 of file ImageTransforms.cs.

ApplyDistortEx()

SimpleDatum MyCaffe.data.ImageTransforms< T >.ApplyDistortEx	(	SimpleDatum	sd,
		DistortionParameter	p
	)

The ApplyDistortEx method applies the distortion policy to the simple datum.

Parameters

sd	Specifies the SimpleDatum to distort.
p	Specifies the distortion parameters that define the distortion policy.

Returns

The distorted SimpleDatum is returned.

Definition at line 426 of file ImageTransforms.cs.

ApplyNoise()

SimpleDatum MyCaffe.data.ImageTransforms< T >.ApplyNoise	(	SimpleDatum	sd,
		NoiseParameter	p
	)

The ApplyNoise method applies the noise policy to the SimpleDatum.

Parameters

sd	Specifies the SimpleDatum for which noise is to be added.
p	Specifies the NoiseParameter that defines the noise policy.

NOTE: This method is not yet complete.

Definition at line 446 of file ImageTransforms.cs.

ApplyResize()

SimpleDatum MyCaffe.data.ImageTransforms< T >.ApplyResize	(	SimpleDatum	sd,
		ResizeParameter	p
	)

The ApplyResize method resizes the SimpleDatum containing an image to a newly resized image as specified by the resize parameter.

Parameters

sd	Specifies the SimpleDatum to resize - must contain a 3 channel image.
p	Specifies the resize parameter to apply.

Returns

The newly resized SimpleDatum is returned.

Definition at line 458 of file ImageTransforms.cs.

InferNewSize()

void MyCaffe.data.ImageTransforms< T >.InferNewSize	(	ResizeParameter	p,
		int	nOldWidth,
		int	nOldHeight,
		out int	nNewWidth,
		out int	nNewHeight
	)

Infer the new shape based on the resize policy.

Parameters

p	Specifies the ResizeParameter with the resize policy.
nOldWidth	Specifies the old width.
nOldHeight	Specifies the old height.
nNewWidth	Specifies the new 'inferred' width.
nNewHeight	Specifies the new 'inferred' width.

Definition at line 128 of file ImageTransforms.cs.

UpdateBBoxByResizePolicy()

NormalizedBBox MyCaffe.data.ImageTransforms< T >.UpdateBBoxByResizePolicy	(	ResizeParameter	p,
		int	nOldWidth,
		int	nOldHeight,
		NormalizedBBox	bbox1
	)

Update the BBox size based on the Resize policy.

Parameters

p	Specifies the ResizeParameter with the resize policy.
nOldWidth	Specifies the old width.
nOldHeight	Specifies the old height.
bbox1	Specifies the BBox to update.

Returns

The update NormalizedBBox is returned.
