SCNet Code

Region matching code is contributed by Kai Han (khan@cs.hku.hk).

Dense matching code is contributed by Rafael S. Rezende (rafael.sampaio_de_rezende@inria.fr).

This code is written in MATLAB, and implements the SCNet[1]. For the dataset, see our project page: http://www.di.ens.fr/willow/research/scnet.

Codes

SCNet_Matconvnet

Additional Matconvnet modules implemented for SCNet. These code should be copied into matconvnet/matlab/ folder.

SCNet

This is the primary net work training and testing code.

  • SCNet_A_init.m, SCNet_AG_init.m, SCNet_AGplus_init.m: initialize the SCNet_A, SCNet_AG, SCNet_AG+.

  • SCNet_A.m, SCNet_AG.m, SCNet_AGplus.m: train SCNet_A, SCNet_AG, SCNet_AG+.

  • eva_PCR_mIoU_SCNet_A.m, eva_PCR_mIoU_SCNet_AG.m, eva_PCR_mIoU_SCNet_AGplus.m: evaluate the trained nets.

  • eva_PCR_mIoU_ImageNet_SCNet_A.m, eva_PCR_mIoU_ImageNet_SCNet_AG.m, eva_PCR_mIoU_ImageNet_SCNet_AGplus.m: evaluate SCNets with ImageNet pretrained parameters, i.e., SCNets without training.

SCNet_Baselines

Comparison code for our SCNet features and HOG features with NAM, PHM and LOM in Proposal Flow [2, 3].

  • NAM_HOG_eva.m, PHM_HOG_eva.m, LOM_HOG_eva.m: evaluate NAM, PHM, and LOM with HOG features.

  • NAM_SCNet_eva.m, PHM_SCNet_eva.m, LOM_SCNet_eva.m: evaluate NAM, PHM, and LOM with learned SCNet features.

  • HOG_SCNet_AG_eva.m: replace the learned SCNet feature by HOG feature in SCNet_AG model.

Data

We used PF-PASCAL, PF-WILLOW, PASCAL Parts and CUB data sets and follows Proposal Flow[2, 3] to generate our trainging data.

Triaining data preparation code is put in PF-PASCAL-code folder.
