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.
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.
