Implementation of Some Deep Hash Algorithms Baseline and Retrieval Demo.
My environment is
python==3.7.0 torchvision==0.5.0 pytorch==1.4.0
You can easily train and test any algorithm just by
python DSH.py
python DPSH.py
python DHN.py
python DSDH.py
If you have any problems, feel free to contact me by email(1142732931@qq.com) or raise an issue.
There are three different configurations for cifar10
- config["dataset"]="cifar10" will use 1000 images (100 images per class) as the query set, 5000 images( 500 images per class) as training set , the remaining 54,000 images are used as database.
- config["dataset"]="cifar10-1" will use 1000 images (100 images per class) as the query set, the remaining 59,000 images are used as database, 5000 images( 500 images per class) are randomly sampled from the database as training set.
- config["dataset"]="cifar10-2" will use 10000 images (1000 images per class) as the query set, 50000 images( 5000 images per class) as training set and database.
You can download NUS-WIDE here
Use data/nus-wide/code.py to randomly select 100 images per class as the query set (2,100 images in total). The remaining images are
used as the database set, from which we randomly sample 500 images per class as the training set (10, 500 images
in total).
You can download ImageNet, NUS-WIDE-m and COCO dataset here where is the data split copy from, or Baidu Pan(Password: hash).
NUS-WIDE-m is different from NUS-WIDE, so i made a distinction.
269,648 images in NUS-WIDE , and 195834 images which are associated with 21 most frequent concepts.
NUS-WIDE-m has 223,496 images,and NUS-WIDE-m is used in HashNet(ICCV2017) and code HashNet caffe and pytorch
download mirflickr , and use ./data/mirflickr/code.py to randomly select 1000 images as the test query set and 4000 images as the train set.

I add some code in DSH.py:
config["pr_curve_path"] = f"log/alexnet/DSH_{config['dataset']}_{bit}.json"
To get the Precision Recall Curve, you should copy the json path "DSH": "../log/alexnet/DSH_cifar10-1_48.json", to precision_recall_curve.py and run this file.
cd utils
python precision_recall_curve.py
It is difficult to implement all by myself, so I made some modifications based on these codes
