Global Self-Attention Networks

no code implementations1 Jan 2021 Zhuoran Shen, Irwan Bello, Raviteja Vemulapalli, Xuhui Jia, Ching-Hui Chen

Based on the proposed GSA module, we introduce new standalone global attention-based deep networks that use GSA modules instead of convolutions to model pixel interactions.

Boosting Image-based Mutual Gaze Detection using Pseudo 3D Gaze

no code implementations15 Oct 2020 Bardia Doosti, Ching-Hui Chen, Raviteja Vemulapalli, Xuhui Jia, Yukun Zhu, Bradley Green

In this work, we focus on the task of image-based mutual gaze detection, and propose a simple and effective approach to boost the performance by using an auxiliary 3D gaze estimation task during the training phase.

An Automatic System for Unconstrained Video-Based Face Recognition

no code implementations10 Dec 2018 Jingxiao Zheng, Rajeev Ranjan, Ching-Hui Chen, Jun-Cheng Chen, Carlos D. Castillo, Rama Chellappa

In this work, we consider challenging scenarios for unconstrained video-based face recognition from multiple-shot videos and surveillance videos with low-quality frames.

Learning from Ambiguously Labeled Face Images

no code implementations15 Feb 2017 Ching-Hui Chen, Vishal M. Patel, Rama Chellappa

To prevent the majority labels from dominating the result of MCar, we generalize MCar to a weighted MCar (WMCar) that handles label imbalance.

Unconstrained Still/Video-Based Face Verification with Deep Convolutional Neural Networks

no code implementations9 May 2016 Jun-Cheng Chen, Rajeev Ranjan, Swami Sankaranarayanan, Amit Kumar, Ching-Hui Chen, Vishal M. Patel, Carlos D. Castillo, Rama Chellappa

Over the last five years, methods based on Deep Convolutional Neural Networks (DCNNs) have shown impressive performance improvements for object detection and recognition problems.

Blur-Aware Disparity Estimation From Defocus Stereo Images

no code implementations ICCV 2015 Ching-Hui Chen, Hui Zhou, Timo Ahonen

We propose a blur-aware disparity estimation method that is robust to the mismatch of focus in stereo images.

Domain-invariant Face Recognition using Learned Low-rank Transformation

no code implementations1 Aug 2013 Qiang Qiu, Guillermo Sapiro, Ching-Hui Chen

We present a low-rank transformation approach to compensate for face variations due to changes in visual domains, such as pose and illumination.
