Member Function Documentation

◆ extractTemplate()

virtual bool cv::linemod::QuantizedPyramid::extractTemplate ( Template templ) const
pure virtual
Python:
retval, templ=cv.linemod_QuantizedPyramid.extractTemplate()

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

Parameters
[out]templThe new template.

◆ pyrDown()

virtual void cv::linemod::QuantizedPyramid::pyrDown ( )
pure virtual
Python:
None=cv.linemod_QuantizedPyramid.pyrDown()

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:
dst=cv.linemod_QuantizedPyramid.quantize([, dst])

Compute quantized image at current pyramid level for online detection.

Parameters
[out]dstThe 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]candidatesCandidate features sorted by score.
[out]featuresDestination vector of selected features.
[in]num_featuresNumber of candidates to select.
[in]distanceHint for desired distance between features.
