InFlux: A Benchmark for Self-Calibration of Dynamic Intrinsics of Video Cameras

NeurIPS 2025poster

Accurately tracking camera intrinsics is crucial for achieving 3D understanding from 2D video. However, most 3D algorithms assume that camera intrinsics stay constant throughout a video, which is often not true for many real-world in-the-wild videos. A major obstacle in this field is a lack of dynam…

Finding Naturally Occurring Physical Backdoors in Image Datasets

NeurIPS 2022accept

Extensive literature on backdoor poison attacks has studied attacks and defenses for backdoors using “digital trigger patterns.” In contrast, “physical backdoors” use physical objects as triggers, have only recently been identified, and are qualitatively different enough to resist most defenses tar…
