Simple Image Search Engine

News

• [2020.06] Updated many parts of the code for CVPR 2020 tutorial

Overview

• Simple image-based image search engine using Keras + Flask. You can launch the search engine just by running two python scripts.
• offline.py: This script extracts a deep-feature from each database image. Each feature is a 4096D fc6 activation from a VGG16 model with ImageNet pre-trained weights.
• server.py: This script runs a web-server. You can send your query image to the server via a Flask web-interface. The server finds similar images to the query by a simple linear scan.
• GPUs are not required.
• Tested on Ubuntu 18.04 and WSL2 (Ubuntu 20.04)

Usage

git clone https://github.com/matsui528/sis.git
cd sis
pip install -r requirements.txt

# Put your image files (*.jpg) on static/img

# Then fc6 features are extracted and saved on static/feature
# Note that it takes time for the first time because Keras downloads the VGG weights.
python offline.py

# Now you can do the search via localhost:5000
python server.py

Advanced: Launch on AWS EC2

• You can easily launch the search engine server on AWS EC2. Please first open the port 5000 and launch an EC2 instance. Note that you need to create a security group such that the port 5000 is opened.
• A middle-level CPU instance is sufficient, e.g., m5.large.
• After you log-in to the instance by ssh, please setup the python environment (e.g., by anaconda).
• Run offline.py and server.py.
• After you run python server.py, you can access the server from your browser via something like http://ec2-XX-XX-XXX-XXX.us-west-2.compute.amazonaws.com:5000
• (Advanced) If you'd like to deploy the system in a secure way, please consider running the search engine with the usual web server, e.g., uWSGI + nginx.
