Model Card for hieradet_d_small_dino-v2-inat21

HieraDet (dynamic window size) small image classification model. The model follows a two-stage training process: first, DINOv2 pretraining, then fine-tuned on the iNaturalist 2021 dataset - https://github.com/visipedia/inat_comp/tree/master/2021.

The model's class-to-index mapping uses original scientific names with full taxonomic rank, a partial mapping to common names can be found here: https://gitlab.com/birder/birder/-/blob/main/public_datasets_metadata/inat21-mapping.json

Note: A 256 x 256 variant of this model is available as hieradet_d_small_dino-v2-inat21-256px.

Model Usage

Image Classification

python

import birder
from birder.inference.classification import infer_image

(net, model_info) = birder.load_pretrained_model("hieradet_d_small_dino-v2-inat21", inference=True)
# Note: A 256x256 variant is available as "hieradet_d_small_dino-v2-inat21-256px"

# Get the image size the model was trained on
size = birder.get_size_from_signature(model_info.signature)

# Create an inference transform
transform = birder.classification_transform(size, model_info.rgb_stats)

image = "path/to/image.jpeg"  # or a PIL image, must be loaded in RGB format
(out, _) = infer_image(net, image, transform)
# out is a NumPy array with shape of (1, 10000), representing class probabilities.

Image Embeddings

python

import birder
from birder.inference.classification import infer_image

(net, model_info) = birder.load_pretrained_model("hieradet_d_small_dino-v2-inat21", inference=True)

# Get the image size the model was trained on
size = birder.get_size_from_signature(model_info.signature)

# Create an inference transform
transform = birder.classification_transform(size, model_info.rgb_stats)

image = "path/to/image.jpeg"  # or a PIL image
(out, embedding) = infer_image(net, image, transform, return_embedding=True)
# embedding is a NumPy array with shape of (1, 768)

Detection Feature Map

python

from PIL import Image
import birder

(net, model_info) = birder.load_pretrained_model("hieradet_d_small_dino-v2-inat21", inference=True)

# Get the image size the model was trained on
size = birder.get_size_from_signature(model_info.signature)

# Create an inference transform
transform = birder.classification_transform(size, model_info.rgb_stats)

image = Image.open("path/to/image.jpeg")
features = net.detection_features(transform(image).unsqueeze(0))
# features is a dict (stage name -> torch.Tensor)
print([(k, v.size()) for k, v in features.items()])
# Output example:
# [('stage1', torch.Size([1, 96, 96, 96])),
#  ('stage2', torch.Size([1, 192, 48, 48])),
#  ('stage3', torch.Size([1, 384, 24, 24])),
#  ('stage4', torch.Size([1, 768, 12, 12]))]
