A Geometry-Driven, Framework-Agnostic Optimization for Object Pose Estimation

Current object pose estimation research remains predominantly model-centric, focusing on architectural innovations and post-processing refinements. This paper introduces a data-centric optimization by proposing a novel, physically grounded rotation representation through principal axes alignment. Our method aligns the...

DF-Iris: Discriminative Texture Discovery for Near-Eye Iris Recognition

Iris recognition in unconstrained near-eye scenarios faces significant challenges due to off-axis gaze and occlusions, where traditional geometry-dependent pipelines relying on explicit segmentation become fragile. To address this limitation, we propose DF-Iris, an end-to-end framework that reformulates recognition fro...

KaleidoEye: A Large-scale Dataset and Benchmark for Slippage Robust Gaze Tracking in HMDs.

Egocentric gaze tracking is essential for immersive interaction on head-mounted displays (HMDs). However, existing studies typically assume a fixed and tightly fitted headset placement, overlooking the inevitable HMD slippage under real-world conditions. Although several datasets with variable wearing positions have be...
