https://github.com/VicenteVivan/geo-clip with ONNX weights to be compatible with Transformers.js.

Usage (Transformers.js)

If you haven't already, you can install the Transformers.js JavaScript library from NPM using:

npm i @xenova/transformers

Example: Perform worldwide image geolocalization.

import { AutoModel, AutoProcessor, RawImage, Tensor, dot, softmax } from '@xenova/transformers';

// Load vision and location models
const model_id = 'Xenova/geoclip-large-patch14';
const vision_model = await AutoModel.from_pretrained(model_id, {
    model_file_name: 'vision_model',
});
const location_model = await AutoModel.from_pretrained(model_id, {
    model_file_name: 'location_model',
    quantized: false,
});

// Load image processor
const processor = await AutoProcessor.from_pretrained('openai/clip-vit-large-patch14');

// Read and preprocess image
const url = 'https://huggingface.co/datasets/Xenova/transformers.js-docs/resolve/main/moraine-lake.png';
const image = await RawImage.fromURL(url);
const vision_inputs = await processor(image);

// Compute image embeddings
const { image_embeds } = await vision_model(vision_inputs);
const norm_image_embeds = image_embeds.normalize().data;

// Define a list of candidate GPS coordinates
// https://github.com/VicenteVivan/geo-clip/blob/main/geoclip/model/gps_gallery/coordinates_100K.csv
const coordinate_data = 'https://huggingface.co/Xenova/geoclip-large-patch14/resolve/main/gps_gallery/coordinates_100K.json';
const gps_data = await (await fetch(coordinate_data)).json();

// Compute location embeddings and compare to image embeddings
const coordinate_batch_size = 512;
const exp_logit_scale = Math.exp(3.681034803390503); // Used for scaling logits
const scores = [];
for (let i = 0; i < gps_data.length; i += coordinate_batch_size) {
    const chunk = gps_data.slice(i, i + coordinate_batch_size);

    const { location_embeds } = await location_model({
        location: new Tensor('float32', chunk.flat(), [chunk.length, 2])
    });

    const norm_location_embeds = location_embeds.normalize().tolist();
    for (const embed of norm_location_embeds) {
        const score = exp_logit_scale * dot(norm_image_embeds, embed);
        scores.push(score);
    }
}

// Get top predictions
const top_k = 50;
const results = softmax(scores)
    .map((x, i) => [x, i])
    .sort((a, b) => b[0] - a[0])
    .slice(0, top_k)
    .map(([score, index]) => ({ index, gps: gps_data[index], score }));

console.log('=======================');
console.log('Top 5 GPS Predictions 📍');
console.log('=======================');
for (let i = 0; i < 5; ++i) {
    console.log(results[i]);
}
console.log('=======================');

Outputs:

As seen on the map, this is indeed the location of Moraine Lake in Canada.

Note: Having a separate repo for ONNX weights is intended to be a temporary solution until WebML gains more traction. If you would like to make your models web-ready, we recommend converting to ONNX using 🤗 Optimum and structuring your repo like this one (with ONNX weights located in a subfolder named onnx).
