models A curious phenomenon in image retrieval

I do image retrieval task with --use_geometric_verification on the code perform_retrieval.py in delg folder. To compare different local feature, I tried to replace the local feature of delg with Superpoint. But the performance is lower than the baseline (do global retrieval only). as far as I am concerned, geometry verification is a commom method to improve the performance.

I wanna know that is this phenomenon normal? Does it means geometry verification can't improve the performance definitely?

the result of Superpoint is shown below:

hard mAP=45.17 mP@k[ 1 5 10] [87.14 71.43 60.29] mR@k[ 1 5 10] [19.29 29.39 36.42] hard_after_gv mAP=41.04 mP@k[ 1 5 10] [84.29 68.57 56.57] mR@k[ 1 5 10] [19.01 27.18 31.21] medium mAP=69.75 mP@k[ 1 5 10] [95.71 92. 86.86] mR@k[ 1 5 10] [10.17 25.94 33.84] medium_after_gv mAP=67.29 mP@k[ 1 5 10] [95.71 91.43 86.14] mR@k[ 1 5 10] [10.19 25.67 33.6 ]

I submit the issue in branch tensorflow\models, so i use the template from https://github.com/tensorflow/models/issues/new/choose. The template you mentioned seems used in tensorflow\tensorflow.

Hi @aruba01 ,

Sorry It was my mistake , default template pointing out to tensorflow\tensorflow.. we will check the issue.

Thanks.
