How a non-traditional background led to cutting-edge XR tech

New AI technique could make minimally invasive surgeries safer and more precise

A new AI technique named xvr enables patient‑specific use of X‑ray imaging for surgical navigation, potentially improving the safety and precision of minimally invasive procedures. The method is applicable in fields such as orthopedics and neurosurgery, where accurate guidance is critical.

XFeat Revisited: Reproducibility and Evaluation of a Lightweight Image Matcher

We present a reproducibility study of XFeat, a lightweight local feature extractor and matcher designed to identify corresponding points across images efficiently on resource-constrained hardware. We re-implement the architecture based on the paper and supplementary material, re-evaluate the authors' released checkpoint alongside our re-implementation, and conduct additional architectural ablations to examine design choices that were not fully justified in the original work.

Bio-SFT: Asymmetric Cortical Guidance and Retinal Adaptation for Robust HDR Reconstruction

Recovering high dynamic range (HDR) radiance from a single standard dynamic range (SDR) image is highly ill-posed. Extreme luminance variation and severe quantization in dark regions make accurate reconstruction challenging, often leading to visual artifacts and color distortions.

LightFuse: Relightable Interactive Gaussian Scene Reconstruction via Multi-Scan Fusion and 2D Gaussian Ray Tracing

arXiv:2608.29269v1 Announce Type: new Abstract: Relightable interactive scene reconstruction aims to build an editable 3D model from scans of different object arrangements and render new layouts unde...
