###Introduction

This repository contains the code for the CVPR paper ‘Sketch Me That Shoe’, which is a deep learning based implementation of fine-grained sketch-based image retrieval.

For more details, please visit our project page: http://www.eecs.qmul.ac.uk/~qian/Project_cvpr16.html

New: Tensorflow implementation can be found here: https://github.com/yuchuochuo1023/Deep_SBIR_tf/tree/master.

###Installation

1. Download the repository

   git clone git@github.com:seuliufeng/DeepSBIR.git

2. Build Caffe and pycaffe

   a. Go to folder $SBIR_ROOT/caffe_sbir

   b. modify the path in Makefile.config, to use this code, you have to compile with python layer

     WITH_PYTHON_LAYER := 1

   c. Compile caffe shell make –j32 && make pycaffe

3. Go to fold $SBIR_ROOT, and run

   source bashsbir

###Run the demo

1. To run the demo, please first download our database and models. Go to the root folder of this project, and run

   chmod +x download_data.sh
   ./download_data.sh

Note: You can also download them manually from our project page: http://www.eecs.qmul.ac.uk/~qian/Project_cvpr16.html

2. Run the demo:

python $SBIR_ROOT/tools/sbir_demo.py

###Re-training the model

1. Go to the root folder of this project

   cd $SBIR_ROOT

2. Run the command

./experiments/train_sbir.sh

Note: Please make sure the initial model ‘/init/sketchnet_init.caffemodel’ be under the folder experiments/. This initial model can be downloaded from our project page.

###Extra comment

1. All provided models and codes are optimised version. And our latest result is shown below:

   Dataset	acc.@1	acc.@10	%corr.
   Shoes	52.17%	92.17%	72.29%
   Chairs	72.16%	98.96%	74.36%

Further explanation: The model we reported in our paper is trained by our originally collected sketches which contain much noise. In order to improve usability, we cleaned the sketch images(removed some noise) after CVPR2016 deadline. You can compare images 'test_shoes_370.png' and '370.jpg' (or 'test_chairs_230.png'/'230.jpg') to see the difference. We re-trained our model using clean sketch images and the new results are listed above. Both the model and dataset we released now is the latest version. Sorry for any confusion we may bring about. If you have further questions, please email q.yu@qmul.ac.uk.

2. This project used codes of the following project:

   Caffe trainnet python wrapper and python data layer

   L2 normalization layer

   Triplet loss
