Seeing the Unseen in Low-light Spike Streams

Published in ECCV 2026, 2025

We propose Diff-SPK, a diffusion-based reconstruction method that leverages generative priors to recover high-quality images from low-light spike streams.

Splats in Splats: Robust and Effective 3D Steganography towards Gaussian Splatting

Published in AAAI 2026, 2026

We propose splats in splats, the first 3DGS steganography framework that embeds 3D content in 3DGS itself without modifying any attributes, via importance-graded SH coefficient encryption and autoencoder-assisted opacity mapping.

CAST: Non-Privileged Clipped Asymmetric Self-Teaching with Advantage Flipping for GRPO

Published in arXiv preprint, 2026

We propose CAST, an answer-free self-distillation method for GRPO-style RLVR that shapes token-level advantages according to trajectory correctness.
