Implementation

Thanks to @mazzzystar and @Young-Flash for their assistance during the development. The discussion can be viewed here.

PicQuery is powered by OpenAI's CLIP model.

First, the images to be searched are encoded into vectors using an image encoder and stored in a database. The text provided by the user during the search is also encoded into a vector. The encoded text vector is then compared with the indexed image vectors to calculate the similarity. The top K images with the highest similarity scores are selected as the query results.

Build & Run

To build this project, you need to obtain a quantized CLIP model.

Run the scripts in this jupyter notebook step by step. When you run into the "You are done" section, you should get the following model files in ./result directory:

clip-image-int8.ort
clip-text-int8.ort

If you don't want to run the scripts, you may directly download them from Google Drive.

Put them into app\src\main\assets and you're ready to go.
