AssemblyHands: Towards Egocentric Activity Understanding via 3D Hand Pose Estimation

no code implementations CVPR 2023 Takehiko Ohkawa, Kun He, Fadime Sener, Tomas Hodan, Luan Tran, Cem Keskin

To obtain high-quality 3D hand pose annotations for the egocentric images, we develop an efficient pipeline, where we use an initial set of manual annotations to train a model to automatically annotate a much larger dataset.

In-Hand 3D Object Scanning from an RGB Sequence

no code implementations CVPR 2023 Shreyas Hampali, Tomas Hodan, Luan Tran, Lingni Ma, Cem Keskin, Vincent Lepetit

As direct optimization over all shape and pose parameters is prone to fail without coarse-level initialization, we propose an incremental approach that starts by splitting the sequence into carefully selected overlapping segments within which the optimization is likely to succeed.

UmeTrack: Unified multi-view end-to-end hand tracking for VR

no code implementations31 Oct 2022 Shangchen Han, Po-Chen Wu, Yubo Zhang, Beibei Liu, Linguang Zhang, Zheng Wang, Weiguang Si, Peizhao Zhang, Yujun Cai, Tomas Hodan, Randi Cabezas, Luan Tran, Muzaffer Akbay, Tsz-Ho Yu, Cem Keskin, Robert Wang

In this paper, we present a unified end-to-end differentiable framework for multi-view, multi-frame hand tracking that directly predicts 3D hand pose in world space.

Neural Correspondence Field for Object Pose Estimation

no code implementations30 Jul 2022 Lin Huang, Tomas Hodan, Lingni Ma, Linguang Zhang, Luan Tran, Christopher Twigg, Po-Chen Wu, Junsong Yuan, Cem Keskin, Robert Wang

Unlike classical correspondence-based methods which predict 3D object coordinates at pixels of the input image, the proposed method predicts 3D object coordinates at 3D query points sampled in the camera frustum.

Fully Understanding Generic Objects: Modeling, Segmentation, and Reconstruction

1 code implementation CVPR 2021 Feng Liu, Luan Tran, Xiaoming Liu

That is, for a 2D image of a generic object, we decompose it into latent representations of category, shape and albedo, lighting and camera projection matrix, decode the representations to segmented 3D shape and albedo respectively, and fuse these components to render an image well approximating the input image.

On Learning Disentangled Representations for Gait Recognition

no code implementations5 Sep 2019 Ziyuan Zhang, Luan Tran, Feng Liu, Xiaoming Liu

The LSTM integrates pose features over time as a dynamic gait feature while canonical features are averaged as a static gait feature.

Towards High-fidelity Nonlinear 3D Face Morphable Model

no code implementations CVPR 2019 Luan Tran, Feng Liu, Xiaoming Liu

By improving the nonlinear 3D morphable model in both learning objective and network architecture, we present a model which is superior in capturing higher level of details than the linear or its precedent nonlinear counterparts.

3D Face Modeling From Diverse Raw Scan Data

1 code implementation ICCV 2019 Feng Liu, Luan Tran, Xiaoming Liu

Traditional 3D face models learn a latent representation of faces using linear subspaces from limited scans of a single database.

On Learning 3D Face Morphable Model from In-the-wild Images

1 code implementation28 Aug 2018 Luan Tran, Xiaoming Liu

To address these problems, this paper proposes an innovative framework to learn a nonlinear 3DMM model from a large set of in-the-wild face images, without collecting 3D face scans.

Nonlinear 3D Face Morphable Model

1 code implementation CVPR 2018 Luan Tran, Xiaoming Liu

As a classic statistical model of 3D facial shape and texture, 3D Morphable Model (3DMM) is widely used in facial analysis, e. g., model fitting, image synthesis.

Gotta Adapt 'Em All: Joint Pixel and Feature-Level Domain Adaptation for Recognition in the Wild

1 code implementation CVPR 2019 Luan Tran, Kihyuk Sohn, Xiang Yu, Xiaoming Liu, Manmohan Chandraker

Recent developments in deep domain adaptation have allowed knowledge transfer from a labeled source domain to an unlabeled target domain at the level of intermediate features or input pixels.

Missing Modalities Imputation via Cascaded Residual Autoencoder

no code implementations CVPR 2017 Luan Tran, Xiaoming Liu, Jiayu Zhou, Rong Jin

To leverage the valuable information in the corrupted data, we propose to impute the missing data by leveraging the relatedness among different modalities.

Representation Learning by Rotating Your Faces

no code implementations31 May 2017 Luan Tran, Xi Yin, Xiaoming Liu

First, the encoder-decoder structure of the generator enables DR-GAN to learn a representation that is both generative and discriminative, which can be used for face image synthesis and pose-invariant face recognition.
