Object Pose Estimation using Patch-Duplet/SIFT Hybrids

Recent years have seen a lot of work on local descrip- tors. In all published comparisons or evaluations, the now quite well-known SIFT-descriptor has been one of the top performers. For the application of object pose estimation, one comparison showed a local descriptor, called the Patch-Duplet, of equal or better performance than SIFT. This paper examines different properties of those two descriptors by forming hybrids between them and extending the object pose tests of the orig- inal Patch-Duplet paper. All tests use real images.
