vehicle image retrieval using k CNNs ensemble method

Vehicle Retrieval

Multi-CNN feature ensemble method.

1. We have trained 4 GoogLeNet with different task, e.g, triplet loss (full image), vehicle_id softmax loss (full image), vehicle_id softmax loss (upper half image) and model_id softmax loss (lower half image).
2. In inference stage, we concat the pool5/7x7_s1 layer feature from the 4 GoogLeNet together. Finally, return the k nearest vehicles.

Competition & Dataset

We used the method in Vehicle Retrieval task of The 3rd National Gradute Contest on Smart-CIty Technology and Creative Design, China. We ranked 1st and won the special prize in the final!

The Dataset used in Vehicle Retrieval task: PKU VehicleID. Note: if you want to use the dataset, go to the website and ask for the download link.

Platform

• CPU or GPU: CPU only
• OS: Windows x64
• DL tool: Caffe
• Compiler: VS2013

Usage

1. Windows Caffe (use this version) setup.
2. Download or git clone the current project.
3. Copy or move vs_vehicle_retrieval_kCNNs folder into caffe/windows and add vehicle_retrieval_kCNNs.vcxproj project into Caffe solution in VS2013, compile it with Release mode.
4. Modify run.bat, mainly set the path. Finally, run run.bat in cmd, you'll get a xml result file.

方法

基于深度学习的多模型集成方法。

平台

CPU，Windows系统，Caffe，VS2013

使用

1. 下载、配置、编译Caffe官方windows版(https://github.com/BVLC/caffe/tree/714d0acad8c66d64ddf7b83b9a239f7efc017894)
2. 下载本工程
3. 将文件夹vs_vehicle_retrieval_kCNNs复制到caffe/windows目录下，并在vs中把vehicle_retrieval_kCNNs.vcxproj项目添加到Caffe解决方案下，使用Release模式编译生成可执行文件。
4. 修改run.bat中的路径，运行它，即可得到实验结果。
