Object Detection Base Model Target Model

Florence-2

Florence 2, introduced in the paper Florence-2: Advancing a Unified Representation for a Variety of Vision Tasks is a multimodal vision model.

You can use Florence 2 to generate object detection annotations for use in training smaller object detection models with Autodistill.

Installation

To use Florence 2 with Autodistill, you need to install the following dependency:

pip3 install autodistill-florence-2

Quickstart (Inference from Base Weights)

from autodistill_florence_2 import Florence2
from autodistill.detection import DetectionOntology
from PIL import Image

# define an ontology to map class names to our Florence 2 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 = Florence2(
    ontology=CaptionOntology(
        {
            "person": "person",
            "a forklift": "forklift"
        }
    )
)

image = Image.open("image.jpeg")
result = base_model.predict('image.jpeg')

bounding_box_annotator = sv.BoundingBoxAnnotator()
annotated_frame = bounding_box_annotator.annotate(
    scene=image.copy(),
    detections=detections
)
sv.plot_image(image=annotated_frame, size=(16, 16))

# label a dataset
base_model.label("./context_images", extension=".jpeg")

Quickstart (Fine-Tune)

from autodistill_florence_2 import Florence2Trainer

model = Florence2Trainer("dataset")
model.train(dataset.location, epochs=10)
