SiftDist Code (C++ and Matlab wrappers)


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.
