Circular Earth Mover Distance
Post @ 0:34:31 | EMD
Matching feature descriptors in vision is essential for stitching and object recognition among others. Since SIFT is based on discretizing the 360-degree wheel of gradient at different scales, it is better to use circular earth mover distance than a straight EMD.
Experiments are reported Circular Earth Mover?s Distance for the comparison of local features
