Description
fuzzy_measure_pairingfuzzy_measure_pairingFuzzyMeasurePairingFuzzyMeasurePairingFuzzyMeasurePairingfuzzy_measure_pairing serves to extract straight edge
pairs that lie perpendicular to the major axis of a
rectangle or an annular arc.
For an explanation of the concept of 1D measuring see the introduction of
chapter 1D Measuring.
The extraction algorithm of fuzzy_measure_pairingfuzzy_measure_pairingFuzzyMeasurePairingFuzzyMeasurePairingFuzzyMeasurePairingfuzzy_measure_pairing
is identical to fuzzy_measure_pairsfuzzy_measure_pairsFuzzyMeasurePairsFuzzyMeasurePairsFuzzyMeasurePairsfuzzy_measure_pairs
(see there for details) with the exception, that it is also possible to
extract interleaving and included pairs using the parameter PairingPairingPairingPairingpairingpairing.
Currently only 'no_restriction'"no_restriction""no_restriction""no_restriction""no_restriction""no_restriction" is available, which returns
all possible edge pairs, allowing interleaving and inclusion of pairs.
Only the best scored NumPairsNumPairsNumPairsNumPairsnumPairsnum_pairs edge pairs are returned, whereas 0
indicates to return all possible found edge combinations.
The selected edges are returned as single points, which lie on the
major axis of the rectangle or annular arc. The corresponding edge
amplitudes are returned in AmplitudeFirstAmplitudeFirstAmplitudeFirstAmplitudeFirstamplitudeFirstamplitude_first and
AmplitudeSecondAmplitudeSecondAmplitudeSecondAmplitudeSecondamplitudeSecondamplitude_second, the fuzzy scores in FuzzyScoreFuzzyScoreFuzzyScoreFuzzyScorefuzzyScorefuzzy_score.
In addition, the distance between each edge pair is returned in
IntraDistanceIntraDistanceIntraDistanceIntraDistanceintraDistanceintra_distance, corresponding to the distance
between EdgeFirst[i] and EdgeSecond[i].
Attention
fuzzy_measure_pairingfuzzy_measure_pairingFuzzyMeasurePairingFuzzyMeasurePairingFuzzyMeasurePairingfuzzy_measure_pairing only returns meaningful results if the
assumptions that the edges are straight and perpendicular to the
major axis of the rectangle or annular arc are fulfilled. Thus, it
should not be used to extract edges from curved objects, for
example. Furthermore, the user should ensure that the rectangle or
annular arc is as close to perpendicular as possible to the edges in
the image. Additionally, SigmaSigmaSigmaSigmasigmasigma must not become larger than
approx. 0.5 * Length1 (for Length1 see
gen_measure_rectangle2gen_measure_rectangle2GenMeasureRectangle2GenMeasureRectangle2GenMeasureRectangle2gen_measure_rectangle2).
It should be kept in mind that fuzzy_measure_pairingfuzzy_measure_pairingFuzzyMeasurePairingFuzzyMeasurePairingFuzzyMeasurePairingfuzzy_measure_pairing ignores
the domain of ImageImageImageImageimageimage for efficiency reasons. If certain
regions in the image should be excluded from the measurement a new
measure object with appropriately modified parameters should be
generated.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
