GLOW: Global Layout Aware Attacks on Object Detection

no code implementations27 Feb 2023 Buyu Liu, BaoJun, Jianping Fan, Xi Peng, Kui Ren, Jun Yu

More desired attacks, to this end, should be able to fool defenses with such consistency checks.

The Story in Your Eyes: An Individual-difference-aware Model for Cross-person Gaze Estimation

1 code implementation27 Jun 2021 Jun Bao, Buyu Liu, Jun Yu

We propose a novel method on refining cross-person gaze prediction task with eye/face images only by explicitly modelling the person-specific differences.

Divide-and-Conquer for Lane-Aware Diverse Trajectory Prediction

no code implementations CVPR 2021 Sriram Narayanan, Ramin Moslemi, Francesco Pittaluga, Buyu Liu, Manmohan Chandraker

Our second contribution is a novel trajectory prediction framework called ALAN that uses existing lane centerlines as anchors to provide trajectories constrained to the input lanes.

Weakly But Deeply Supervised Occlusion-Reasoned Parametric Road Layouts

no code implementations CVPR 2022 Buyu Liu, Bingbing Zhuang, Manmohan Chandraker

We propose an end-to-end network that takes a single perspective RGB image of a complex road scene as input, to produce occlusion-reasoned layouts in perspective space as well as a parametric bird's-eye-view (BEV) space.

Uncertainty-Aware Physically-Guided Proxy Tasks for Unseen Domain Face Anti-spoofing

no code implementations28 Nov 2020 Junru Wu, Xiang Yu, Buyu Liu, Zhangyang Wang, Manmohan Chandraker

Face anti-spoofing (FAS) seeks to discriminate genuine faces from fake ones arising from any type of spoofing attack.

SMART: Simultaneous Multi-Agent Recurrent Trajectory Prediction

no code implementations ECCV 2020 Sriram N. N, Buyu Liu, Francesco Pittaluga, Manmohan Chandraker

Our second contribution is a novel method that generates diverse predictions while accounting for scene semantics and multi-agent interactions, with constant-time inference independent of the number of agents.

Active Adversarial Domain Adaptation

no code implementations16 Apr 2019 Jong-Chyi Su, Yi-Hsuan Tsai, Kihyuk Sohn, Buyu Liu, Subhransu Maji, Manmohan Chandraker

Our approach, active adversarial domain adaptation (AADA), explores a duality between two related problems: adversarial domain alignment and importance sampling for adapting models across domains.

Active Learning for Human Pose Estimation

no code implementations ICCV 2017 Buyu Liu, Vittorio Ferrari

Annotating human poses in realistic scenes is very time consuming, yet necessary for training human pose estimators.

Learning Dynamic Hierarchical Models for Anytime Scene Labeling

no code implementations11 Aug 2016 Buyu Liu, Xuming He

With increasing demand for efficient image and video analysis, test-time cost of scene parsing becomes critical for many large-scale or time-sensitive vision applications.

Multiclass Semantic Video Segmentation With Object-Level Active Inference

no code implementations CVPR 2015 Buyu Liu, Xuming He

To scale up our method, we adopt an active inference strategy to improve the efficiency, which adaptively selects object subgraphs in the object-augmented dense CRF.
