This version retains the original model weights and architecture, with the exception of treating the original CLS token as a REG token. It is a general-purpose visual backbone. See: <https://huggingface.co/facebook/PE-Spatial-S16-512> for further details. ## Model Details - **Model Type:** Image classification and detection backbone - **Model Stats:** - Params (M): 22.0 - Input image size: 512 x 512 - **Papers:** - An Image is Worth 16x16 Words: Transformers for Image Recognition at Scale: <https://arxiv.org/abs/2010.11929> - Rotary Position Embedding for Vision Transformer: <https://arxiv.org/abs/2403.13298> - Perception Encoder: The best visual embeddings are not at the output of the network: <https://arxiv.org/abs/2504.13181> ## Model Usage ### Image Embeddings ```python import birder from birder.inference.classification import infer_image (net, model_info) = birder.load_pretrained_model("rope_i_vit_reg1_s16_pn_npn_avg_c1_pe-spatial", 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, 384) ``` ### Detection Feature Map ```python from PIL import Image import birder (net, model_info) = birder.load_pretrained_model("rope_i_vit_reg1_s16_pn_npn_avg_c1_pe-spatial", 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: # [('neck', torch.Size([1, 384, 32, 32]))] ``` ## Citation `...
