Content-Based Image Retrieval

Introduction

This is my project built for the Content-based Image Retrieval problem. In this project, I use the algorithm of indexing and searching Faiss (Facebook). Simultaneously combine many feature extraction methods for comparison and evaluation (RGBHistogram, Local Binary Pattern, VGG16, ResNet50).

Problem

  • Input: A collection of information resources (image database), a query image
  • Output: A ranked list of images that are most similar to the query image, with the most similar image at the top of the list

I use the faiss library created by Facebook. The weights of the VGG16 and Resnet50 networks are taken from the pre-trained model of torchvision.models.

Prepare the environment

  1. python==3.8.16

  2. Install PyTorch-cuda==11.7 following official instruction:

     conda install pytorch torchvision torchaudio pytorch-cuda=11.7 -c pytorch -c nvidia
    
  3. Install Facebook faiss:

     conda install -c conda-forge faiss-gpu
    
  4. Install the necessary dependencies by running:

     pip install -r requirements.txt
    

Prepare the dataset

  1. Put the downloaded The Paris Dataset (or link Kaggle) in ./data/paris

  2. Put the downloaded groundtruth in ./data/groundtruth

Please organize your dataset following this structure:

Running the code

Feature extraction (Indexing)

python indexing.py --feature_extractor Resnet50

The Resnet50.index.bin file will be at Main-folder/dataset/feature.

Evaluation

Evaluation on query set

python ranking.py --feature_extractor Resnet50

Compute Mean Average Precision (MAP):

python evaluate.py --feature_extractor Resnet50

Run demo with streamlit interface:

streamlit run demo.py

Addition

You can modify the config like feature_extractor (RGBHistogram, LBP, VGG16, Resnet50), batch_size, top_k, ...
