The code computes the SiftDist distance between SIFT (Scale Invariant Feature Transform)
descriptors and also match between SIFT descriptors. The approach was described in the paper: "A
Linear Time Histogram Metric for Improved SIFT Matching" [,
].
The first version is the one from the paper. Newer versions are improvements and will give different results.
FastEMD -
code that computes EMD with any thresholded distance very fast.
Quadratic Chi (QC) -
code that computes the new Quadratic Chi histogram distances (proposed at ECCV 2010) very fast.
