Diffusion for image retrieval

This is a Matlab script for our paper:

A. Iscen, G. Tolias, Y. Avrithis, T. Furon, O. Chum. "Efficient Diffusion on Region Manifolds: Recovering Small Objects with Compact CNN Representations", CVPR 2017

Execution

Run the following script:

>> run_test

We provide the descriptors used in our paper and also the necessary ground-truth files for mAP evaluation. In addition to that, we also make available the approximate kNN graph computed off-line with Dong et al. [10] for large-scale datasets. All the required files are stored in the link below and will be downloaded automatically when the script run_test.m is run.

ftp://ftp.irisa.fr/local/texmex/corpus/diffusion/

Optional but recommended prerequisite: Yael Library http://yael.gforge.inria.fr/

All kNN computation will be done with Yael Library if it is found in the path. Even though this is not strictly required, we advise that Yael is installed for efficiency purposes.

Any questions or comments, should be addressed to ahmet.iscen@inria.fr
