Inrecentyears,three-dimensional(3D)objectrecognitiontechnologyhasattractedincreasingattentionfromresearchersduetoitscrucialsignificanceinvariousimagingapplications.Phaseinformationisacriticalfactorforfeatureextractionin3Dobjectrecognitionbecauseitcarriescrucialinformationabouttheintensityandpositionoftheobject.Inthispaper,weexploredtheroleofphasefeaturesin3Dobjectrecognition.Specifically,wediscussedtheconceptofphasefeatures,theirsignificancein3Dobjectrecognition,andtheiruseinextractingfeaturesforobjectrecognition.Furthermore,wereviewedseveralmethodsandtechniquesthatutilizephasefeaturesin3Dobjectrecognitionalongwiththeiradvantagesandlimitations.
Introduction
Three-dimensional(3D)objectrecognitionhasemergedasasignificantresearchareaduetoitsinherentadvantagesoverotherrecognitiontechniques.Incontrasttotwo-dimensional(2D)objectrecognition,3Dobjectrecognitioninvolvesusingvolumetricdataandhasahigherdegreeoffreedomtodistinguishobjectsbasedontheiruniquefeatures.Oneofthecriticalfactorsaffectingtheperformanceof3Dobjectrecognitionistheextractionoffeaturesfrom3Ddata.Inthisregard,phasefeatureshavegainedincreasingpopularityduetotheirabilitytoencodeboththepositionandintensityinformationoftheobject.
Phasefeaturesrefertothedistributionofphasevaluesacrosstheboundariesofanobjectina3Dvolume.ThephaseinformationcanbeobtainedbyapplyingtheFouriertransformto3Ddata,andphasecongruencymeasurescanbeusedtoextractphasefeatures.Phasefeaturesprovidearobustmeasureoftheobject'sshapeandtexture,whichmakesthemavaluabletoolin3Dobjectrecognition.
SignificanceofPhaseFeaturesin3DObjectRecognition
Phasefeaturesplayacriticalrolein3Dobjectrecognitionbyprovidingcomprehensiveinformationabouttheobject'sappearanceandposition.Traditionalfeatureextractionmethods,suchasshapeortexturedescriptors,maynotbesufficientincapturingthecompleteinformationabout3Dobjects.Phasefeaturescanprovideadditionalinformationthatcanenhanceobjectrecognitionaccuracy.
