Morphable Detector for Object Detection on Demand

1 code implementation ICCV 2021 Xiangyun Zhao, Xu Zou, Ying Wu

Once an MD is learned, it is able to use a few samples of a novel class to directly compute its prototype to fulfill the online morphing process.

Contrastive Learning for Label Efficient Semantic Segmentation

no code implementations ICCV 2021 Xiangyun Zhao, Raviteja Vemulapalli, Philip Andrew Mansfield, Boqing Gong, Bradley Green, Lior Shapira, Ying Wu

While recent Convolutional Neural Network (CNN) based semantic segmentation approaches have achieved impressive results by using large amounts of labeled training data, their performance drops significantly as the amount of labeled data decreases.

Object Detection with a Unified Label Space from Multiple Datasets

no code implementations ECCV 2020 Xiangyun Zhao, Samuel Schulter, Gaurav Sharma, Yi-Hsuan Tsai, Manmohan Chandraker, Ying Wu

To address this challenge, we design a framework which works with such partial annotations, and we exploit a pseudo labeling approach that we adapt for our specific case.

Recognizing Part Attributes with Insufficient Data

1 code implementation ICCV 2019 Xiangyun Zhao, Yi Yang, Feng Zhou, Xiao Tan, Yuchen Yuan, Yingze Bao, Ying Wu

Although great progress has been made to apply object-level recognition, recognizing the attributes of parts remains less applicable since the training data for part attributes recognition is usually scarce especially for internet-scale applications.

Pseudo Mask Augmented Object Detection

no code implementations CVPR 2018 Xiangyun Zhao, Shuang Liang, Yichen Wei

In this work, we present a novel and effective framework to facilitate object detection with the instance-level segmentation information that is only supervised by bounding box annotation.

Peak-Piloted Deep Network for Facial Expression Recognition

no code implementations24 Jul 2016 Xiangyun Zhao, Xiaodan Liang, Luoqi Liu, Teng Li, Yugang Han, Nuno Vasconcelos, Shuicheng Yan

Objective functions for training of deep networks for face-related recognition tasks, such as facial expression recognition (FER), usually consider each sample independently.
