Unveiling the Invisible: Reasoning Complex Occlusions Amodally with AURA

no code implementations13 Mar 2025 Zhixuan Li, Hyunse Yoon, SangHoon Lee, Weisi Lin

To address these limitations, we propose a novel task named amodal reasoning segmentation, aiming to predict the complete amodal shape of occluded objects while providing answers with elaborations based on user text input.

Camera-Driven Representation Learning for Unsupervised Domain Adaptive Person Re-identification

no code implementations ICCV 2023 Geon Lee, SangHoon Lee, Dohyung Kim, Younghoon Shin, Yongsang Yoon, Bumsub Ham

To address the camera bias problem, we also introduce a camera-diversity (CD) loss encouraging person images of the same pseudo label, but captured across various cameras, to involve more for discriminative feature learning, providing person representations robust to inter-camera variations.
