Disentangled Lifespan Face Synthesis

no code implementations ICCV 2021 Sen He, Wentong Liao, Michael Ying Yang, Yi-Zhe Song, Bodo Rosenhahn, Tao Xiang

The generated face image given a target age code is expected to be age-sensitive reflected by bio-plausible transformations of shape and texture, while being identity preserving.

Spatial-Temporal Transformer for Dynamic Scene Graph Generation

1 code implementation ICCV 2021 Yuren Cong, Wentong Liao, Hanno Ackermann, Bodo Rosenhahn, Michael Ying Yang

Compared to the task of scene graph generation from images, it is more challenging because of the dynamic relationships between objects and the temporal dependencies between frames allowing for a richer semantic interpretation.

Text to Image Generation with Semantic-Spatial Aware GAN

1 code implementation CVPR 2022 Kai Hu, Wentong Liao, Michael Ying Yang, Bodo Rosenhahn

Text-to-image synthesis (T2I) aims to generate photo-realistic images which are semantically consistent with the text descriptions.

Context-Aware Layout to Image Generation with Enhanced Object Appearance

1 code implementation CVPR 2021 Sen He, Wentong Liao, Michael Ying Yang, Yongxin Yang, Yi-Zhe Song, Bodo Rosenhahn, Tao Xiang

We argue that these are caused by the lack of context-aware object and stuff feature encoding in their generators, and location-sensitive appearance representation in their discriminators.

Exploring Dynamic Context for Multi-path Trajectory Prediction

2 code implementations30 Oct 2020 Hao Cheng, Wentong Liao, Xuejiao Tang, Michael Ying Yang, Monika Sester, Bodo Rosenhahn

In our framework, first, the spatial context between agents is explored by using self-attention architectures.

LR-CNN: Local-aware Region CNN for Vehicle Detection in Aerial Imagery

no code implementations28 May 2020 Wentong Liao, Xiang Chen, Jingfeng Yang, Stefan Roth, Michael Goesele, Michael Ying Yang, Bodo Rosenhahn

This strengthens the local feature invariance for the resampled features and enables detecting vehicles in an arbitrary orientation.

Image Captioning through Image Transformer

2 code implementations29 Apr 2020 Sen He, Wentong Liao, Hamed R. -Tavakoli, Michael Yang, Bodo Rosenhahn, Nicolas Pugeault

Inspired by the successes in text analysis and translation, previous work have proposed the \textit{transformer} architecture for image captioning.

FairNN- Conjoint Learning of Fair Representations for Fair Decisions

1 code implementation5 Apr 2020 Tongxin Hu, Vasileios Iosifidis, Wentong Liao, Hang Zhang, Michael YingYang, Eirini Ntoutsi, Bodo Rosenhahn

In this paper, we propose FairNN a neural network that performs joint feature representation and classification for fairness-aware learning.

MCENET: Multi-Context Encoder Network for Homogeneous Agent Trajectory Prediction in Mixed Traffic

1 code implementation14 Feb 2020 Hao Cheng, Wentong Liao, Michael Ying Yang, Monika Sester, Bodo Rosenhahn

In inference time, we combine the past context and motion information of the target agent with samplings of the latent variables to predict multiple realistic trajectories in the future.

NODIS: Neural Ordinary Differential Scene Understanding

1 code implementation ECCV 2020 Cong Yuren, Hanno Ackermann, Wentong Liao, Michael Ying Yang, Bodo Rosenhahn

Detected objects, their labels and the discovered relations can be used to construct a scene graph which provides an abstract semantic interpretation of an image.

Target-Tailored Source-Transformation for Scene Graph Generation

no code implementations3 Apr 2019 Wentong Liao, Cuiling Lan, Wen-Jun Zeng, Michael Ying Yang, Bodo Rosenhahn

We further explore more powerful representations by integrating language prior with the visual context in the transformation for the scene graph generation.

Security Event Recognition for Visual Surveillance

no code implementations26 Oct 2018 Michael Ying Yang, Wentong Liao, Chun Yang, Yanpeng Cao, Bodo Rosenhahn

The experimental results show that the proposed approach outperforms the state-of-the-art methods and effective in recognizing complex security events.

Temporally Object-based Video Co-Segmentation

no code implementations9 Feb 2018 Michael Ying Yang, Matthias Reso, Jun Tang, Wentong Liao, Bodo Rosenhahn

Therefore, we formulate a graphical model to select a proposal stream for each object in which the pairwise potentials consist of the appearance dissimilarity between different streams in the same video and also the similarity between the streams in different videos.

Video Event Recognition and Anomaly Detection by Combining Gaussian Process and Hierarchical Dirichlet Process Models

no code implementations9 Feb 2018 Michael Ying Yang, Wentong Liao, Yanpeng Cao, Bodo Rosenhahn

In our framework, three levels of video events are connected by Hierarchical Dirichlet Process (HDP) model: low-level visual features, simple atomic activities, and multi-agent interactions.

Triplet-based Deep Similarity Learning for Person Re-Identification

1 code implementation9 Feb 2018 Wentong Liao, Michael Ying Yang, Ni Zhan, Bodo Rosenhahn

Moreover, we trained the model jointly on six different datasets, which differs from common practice - one model is just trained on one dataset and tested also on the same one.

Natural Language Guided Visual Relationship Detection

no code implementations16 Nov 2017 Wentong Liao, Lin Shuai, Bodo Rosenhahn, Michael Ying Yang

Most of the existing works treat this task as a pure visual classification task: each type of relationship or phrase is classified as a relation category based on the extracted visual features.

On Support Relations and Semantic Scene Graphs

no code implementations19 Sep 2016 Michael Ying Yang, Wentong Liao, Hanno Ackermann, Bodo Rosenhahn

In contrast to previous methods for extracting support relations, the proposed approach generates more accurate results, and does not require a pixel-wise semantic labeling of the scene.
