Model summary

WildRayZer is a self-supervised feed-forward framework for novel view synthesis (NVS) in dynamic in-the-wild videos where both the camera and scene objects move. It extends the static NVS model RayZer to dynamic environments by adding:

1. a learned motion mask estimator that flags dynamic regions per input view, trained by distilling pseudo-masks from the residual between a static renderer and the observed frames (DINOv3 + SSIM + co-segmentation + GrabCut);
2. a masked 3D scene encoder that replaces dynamic image tokens with a learnable noise embedding before scene aggregation (MAE-style token masking).

All supervision is self-supervised — no ground-truth depth, camera poses, or motion masks are used. Given a set of unposed, uncalibrated dynamic images, the model predicts camera parameters and motion masks and renders novel static views in a single feed-forward pass.

This checkpoint

The K=2 configuration matches the sparse-view setting used in the paper's main D-RE10K and D-RE10K-iPhone benchmarks. 3- and 4-input-view variants can be reproduced by retraining with the same pipeline — see training details.

How to use

Download the checkpoint and run the reference demo:

from huggingface_hub import hf_hub_download

ckpt_path = hf_hub_download(
    repo_id="uva-cv-lab/wildrayzer-2view",
    filename="wildrayzer_2view.pt",
)
# Pass ckpt_path to the WildRayZerDemo class or to inference.py
# via --config configs/wildrayzer_inference.yaml.

The full inference pipeline, Gradio demo, and training code live in the companion repo. A ready-to-deploy Space layout is provided under demo/ in that repo.

Hardware requirements: CUDA GPU with ≥ 40 GB VRAM (the motion-mask predictor fuses DINOv3 ViT-7B patch features with image/Plücker tokens at inference time — this 7B backbone is a hard dependency, not optional). The author will soon provide an alternative.
