MetaCLIP

Object Detection Base Model

What is MetaClip?

MetaCLIP, developed by Meta AI Research, is a computer vision model trained using pairs of images and text. The model was described in the Demystifying CLIP Data paper. You can use MetaCLIP with autodistill for image classification.

Installation

To use MetaCLIP with autodistill, you need to install the following dependency:

pip3 install autodistill-metaclip

Quickstart

get predictions

from autodistill_metaclip import MetaCLIP

# define an ontology to map class names to our MetaCLIP prompt
# the ontology dictionary has the format {caption: class}
# where caption is the prompt sent to the base model, and class is the label that will
# be saved for that caption in the generated annotations
# then, load the model
base_model = MetaCLIP(
    ontology=CaptionOntology(
        {
            "person": "person",
            "a forklift": "forklift"
        }
    )
)

results = base_model.predict("./image.png")
print(results)

calculate and compare embeddings

from autodistill_metaclip import MetaCLIP

base_model = MetaCLIP(None)

text = base_model.embed_text("coffee")
image = base_model.embed_image("coffeeshop.jpg")

print(base_model.compare(text, image))
