Learning Discriminative and Transformation Covariant Local Feature Detectors

This code is the training and evaluation code for our CVPR 2017 paper. It includes the implement of a translation covariant local feature detector. The affine covariant model will be added in the future.

@inproceedings{zhang2017learning, title={Learning Discriminative and Transformation Covariant Local Feature Detectors}, author={Zhang, Xu and Yu, Felix X. and Karaman, Svebor and Chang, Shih-Fu}, booktitle={CVPR}, year={2017} }

The code is tested on Ubuntu 14.04

Requirement

Python package:

tensorflow>1.0.0, tqdm, cv2, exifread, skimage, glob

Usage

Get the data

Download data from https://www.dropbox.com/s/l7a8zvni6ia5f9g/datasets.tar.gz?dl=0

and put the extract the data to ./data/

Run the code

Change Matlab link in all the files in ./script/

cd ./script

Generate transformed patch and train the model

./batch\_run_train.sh

Extract local feature point

./batch\_run_test.sh

Evaluate the performance

./batch\_run_eval.sh
