TPAMI, 2018.

Meanwhile, this repository also provides the implementation of AMVH as described in the papers:

AMVH: Asymmetric Multi-Valued Hashing
Cheng Da, Shibiao Xu, Kun Ding, Gaofeng Meng, Shiming Xiang, Chunhong Pan
CVPR, 2017.

Prerequisites

Linux 16.04.5 NVIDIA GPU + CUDA-8.0 and corresponding CuDNN

Caffe

Matlab 2015b

Installation Guide

You need to compile the modified Caffe library in this repository. You can consult the generic Caffe installation guide.

When the dependencies of Caffe are installed, try:

make

If there are no error messages, then you can compile and install the matlab wrappers:

make matcaffe

Usage

run AMVH for AMVH: Asymmetric Multi-Valued Hashing on ESP-GAME

cd NAMVH
matlab -r -nodesktop run_AMVH on ESP-GAME with 8-bit codes.

results

maps =

0.4362    0.4906
0.4953    0.5190

noted: maps(1,1) = AMVH_bin; maps(1,2) = AMVH_real; maps(2,2) = AMVH_mul

run NAMVH for Nonlinear Asymmetric Multi-Valued Hashing on ESP-GAME with 8-bit codes.

cd NAMVH
matlab -r -nodesktop run_NAMVH

results

maps =

0.4822    0.5045
0.5208    0.5599

noted: maps(1,1) = NAMVH_1^b; maps(1,2) = NAMVH_1^r; maps(2,2) = NAMVH_{10}^r

Datasets

We provide ESP-GAME dataset ./data to test our codes.
