inlinevirtual

Member Function Documentation

extractTemplate()

virtual bool cv::linemod::QuantizedPyramid::extractTemplate ( Template &  templ ) const

pure virtual

Python:
	cv.linemod_QuantizedPyramid.extractTemplate(		) ->	retval, templ

Extract most discriminant features at current pyramid level to form a new template.

Parameters

[out]

templ

The new template.

pyrDown()

virtual void cv::linemod::QuantizedPyramid::pyrDown ( )

pure virtual

Python:
	cv.linemod_QuantizedPyramid.pyrDown(		) ->	None

Go to the next pyramid level.

Todo:

Allow pyramid scale factor other than 2

quantize()

virtual void cv::linemod::QuantizedPyramid::quantize ( Mat &  dst ) const

pure virtual

Python:
	cv.linemod_QuantizedPyramid.quantize(	[, dst]	) ->	dst

Compute quantized image at current pyramid level for online detection.

Parameters

[out]

dst

The destination 8-bit image. For each pixel at most one bit is set, representing its classification.

selectScatteredFeatures()

static void cv::linemod::QuantizedPyramid::selectScatteredFeatures ( const std::vector< Candidate > &  candidates, std::vector< Feature > &  features, size_t  num_features, float  distance  )

staticprotected

Choose candidate features so that they are not bunched together.

Parameters

[in]	candidates	Candidate features sorted by score.
[out]	features	Destination vector of selected features.
[in]	num_features	Number of candidates to select.
[in]	distance	Hint for desired distance between features.
