This repo contains implementation of MagicLens. The code here uses Jax and Flax. Note that the current implementation does not yet support training. Refer to the website for dataset examples.
We introduce MagicLens, a series of self-supervised image retrieval models that support open-ended instructions. The core thesis of MagicLens is that text instructions can enable retrieving images with richer relations beyond visual similarity. MagicLens is built on a key novel insight: image pairs that naturally occur on the same web pages contain a wide range of implicit relations (e.g., inside view of), and we can bring those implicit relations explicit by synthesizing instructions via large multimodal models (LMMs) and large language models (LLMs). Trained on 36.7M (query image, instruction, target image) triplets with rich semantic relations mined from the web, MagicLens achieves comparable or better results on eight benchmarks of various image retrieval tasks than prior state-of-the-art (SOTA) methods. Remarkably, it outperforms previous SOTA but with a 50× smaller model size on multiple benchmarks. Additional human analyses on a 1.4M-image unseen corpus further demonstrate the diversity of search intents supported by MagicLens.
conda create --name magic_lens python=3.9
conda activate magic_lens
git clone https://github.com/google-research/scenic.git
cd scenic
pip install .
pip install -r scenic/projects/baselines/clip/requirements.txt
# you may need to install corresponding GPU version of jax following https://jax.readthedocs.io/en/latest/installation.html
# e.g.,
# # CUDA 12 installation
# Note: wheels only available on linux.
# pip install --upgrade "jax[cuda12_pip]" -f https://storage.googleapis.com/jax-releases/jax_cuda_releases.html
# # CUDA 11 installation
# Note: wheels only available on linux.
# pip install --upgrade "jax[cuda11_pip]" -f https://storage.googleapis.com/jax-releases/jax_cuda_releases.html
Download model via:
cd .. # in main folder `magiclens`
# you may need to use `gcloud auth login` for access, any gmail account should work.
gsutil cp -R gs://gresearch/magiclens/models ./
OR via google drive
Please follow each dataset folder in ./data. Currently we have successfully tested FIQ, CIRCO, and DTIN:
python inference.py
--model_size large
--model_path ./models/magic_lens_clip_large.pkl
--dataset circo
Due to the weight conversion, the performance may be slightly different:
In CIRCO
| Model | map@5 | map@10 | map@25 | map@50 |
|---|---|---|---|---|
| Prior SOTA | 26.8 | 27.6 | 30.0 | 31.0 |
| Base (original) | 23.1 | 23.8 | 25.8 | 26.7 |
| Base (converted) | 22.3 | 23.2 | 25.0 | 26.0 |
| Large (original) | 29.6 | 30.8 | 33.4 | 34.4 |
| Large (converted) | 29.5 | 30.8 | 33.2 | 34.3 |
