14.1.97.1.1.1.1.1.43m32493 CDVS: Entropy Enhanced AKULA for Key Points Aggregation [Abhishek Nagar, Zhu Li, Gaurav Srivastava, Kyungmo Park]

Similar to m31491 (k-means, distance matrix) + entropy from eigenvalues (new element). New distance: old AKLUA distance + entropy only. Gain for 1a, 1b and 1c (global only). Akula matching is very fast. 90 sec for Akula and 100 sec. No full set of results was available.

14.1.97.1.1.1.1.1.44m32536 GRASF - Grassmann Subspace Feature for Key Points Aggregation [Zhu Li, Abhishek Nagar, Gaurav Srivastava, Kyungmo Park]

SIFT -> Feature selection, dim reduction (PCA 128->32), Covariance Computing. Stiefle and Grassmainnian subspace. Grassmannian bette ras invariant. Distance – principla angle L2. Below 1% better cmp to SCFV (global only). Size 500 bytes. May include second order. No full set of results available yet.

14.1.97.1.1.1.1.1.45m32544 CDVS: ALP Acceleration with Box Filtering [Gaurav Srivastava, Zhu Li, Abhishek Nagar, Kyungmo Park]

Acceleration of the filtering in ALP via Box filter. No full set of results was available.
