DenseMarks

A PyTorch implementation for dense UVW coordinate prediction from human head images using DINOv3 backbone with DPT head architecture.

Overview

DenseMarks predicts per-pixel positions in canonical space (cube [0, 1]³) from human head images.

Input: RGB images of size 512×512 pixels

Output: UVW coordinates tensor (B, 3, 512, 512) with values in [0, 1]

Prerequisites

• Python 3.8+
• PyTorch 1.12+
• CUDA (optional, for GPU acceleration)

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/densemarks.git
   cd densemarks
   

2. Install DINOv3 submodule:

   git clone https://github.com/facebookresearch/dinov3 third_party_dinov3
   

3. Modify DINOv3 for compatibility:

   sed -i '/dinov3\.hub\.segmentors/s/^/#/' third_party_dinov3/hubconf.py
   

4. Install dependencies:

   pip install torch transformers numpy
   

5. Download model weights from Hugging Face:

   from dense_marks_model import DenseMarksModel, read_image
   from huggingface_hub import hf_hub_download
   model = DenseMarksModel(hf_hub_download("diddone/densemarks", "model.safetensors"))
   images = read_image("assets/00000.png") # rgb, 512x512
   uvw = model(images) # Predict UVW coordinates
