Multi‐Object Matching

Multi-Object Matching

runJointMatch

Inputs

• pMatch: pairwise matching results, numpy array of pairwiseMatches class
• C: 2xM coordinate matrix
• M = total number of keypoints in image collection
• method: matching method to use (als or pg)
• univsize: how many points per image

Outputs

• jMatch: joint matching result, numpy array of pairwiseMatches class
• jmInfo: joint matching info, numpy array of jointMatchInfo
• tInfo: joint matching runtime (s)

Other Method Calls

• matchALS
• proposedMethod
• spectralMatch

Joint Matching Methods

MatchALS

M_out, eigV, tInfo, iter = matchALS(vM, nFeature, Size)

Proposed Method

M_out, eigV, tInfo, Z = proposedMethod(vM, C, nFeature, Size)

Spectral

M_out, eigV, tInfo = spectralMatch(vM, nFeature, Size)

Note: broken! due to eigenvector ambiguities in the rounding() function
