3. CE3: Normative aspects of key point extraction

14.1.97.1.1.1.1.1.34m32242 Sisvel Technology response to CE3: Normative aspects of the keypoint detection [Massimo Mattelliano, Giovanni Ballocca, Alessandra Mosca]

Testing interporability of openCV SIFT, VLFeat SIFT, OpenCV ORB vs ALP, using only deafult parameters, without retraining.

The verification test (OpenCV- SIFT vs OpenCV-SIFT) resulted in a high false alarm rate for some bit rates e.g. TPR – 8 KB (16.33%), 16 kB (26%)

Interoperability (TPR %):

• 
  ALP vs SIFT VL-Feat: 90.8%
  
• 
  ALP vs SIFT OpenCV: 0.26%
  
• 
  ALP vs ORB : 0.008%
  

Conclusion on Interoperability:

• 
  ALP and SIFT VLFeat are reasonably interoperable.
  
• 
  No interoperability was achieved between SIFT-VLFeat and SIFT – OpenCV.

14.1.97.1.1.1.1.1.36m32251 CDVS: ETRI’s comments on CE3 [Seungjae Lee, Sang-il Na, Keundong Lee, Weon-Geun Oh]

This contained a suggestion on how to test interoperability – based on two rules 1) all other modules should not be changed or retrained, 2) changes to the feature selection scheme may be introduced to keep interoperability.

Comments: Even if two implementations for operation X are interoperable, it does not mean that any method to do X is interoperable.

14.1.97.1.1.1.1.1.37m32264 Peking University Response to CE3: Interoperability study towards minimum normative part of detector [Jie Chen, Ling-Yu Duan, Tiejun Huang, Wen Gao]

Investigation of interoperability between ALP, BFLoG_ALP and BFLoG, showing interoperability with the margin of: TPR: +/- 0.9% and mAP +/- 2.15%.

The BFLoG_ALP pipeline is the same as m32263 considered in CE1.

The same proposal as m32263; this has been already considered in CE-1. There are no new technical elements but new information about interoperability.

Consensus: Even if two implementations for operation X are interoperable it does not mean that any method to do X is interoperable.

Cross-check; successful.

Cross-check; successful.
