DAP: Detection-Aware Pre-training with Weak Supervision

1 code implementation CVPR 2021 Yuanyi Zhong, JianFeng Wang, Lijuan Wang, Jian Peng, Yu-Xiong Wang, Lei Zhang

This paper presents a detection-aware pre-training (DAP) approach, which leverages only weakly-labeled classification-style datasets (e. g., ImageNet) for pre-training, but is specifically tailored to benefit object detection tasks.

Boosting Weakly Supervised Object Detection with Progressive Knowledge Transfer

1 code implementation ECCV 2020 Yuanyi Zhong, Jian-Feng Wang, Jian Peng, Lei Zhang

In this paper, we propose an effective knowledge transfer framework to boost the weakly supervised object detection accuracy with the help of an external fully-annotated source dataset, whose categories may not overlap with the target domain.

Disentangling Controllable Object through Video Prediction Improves Visual Reinforcement Learning

no code implementations21 Feb 2020 Yuanyi Zhong, Alexander Schwing, Jian Peng

In many vision-based reinforcement learning (RL) problems, the agent controls a movable object in its visual field, e. g., the player's avatar in video games and the robotic arm in visual grasping and manipulation.

Towards End-to-End Face Recognition through Alignment Learning

no code implementations25 Jan 2017 Yuanyi Zhong, Jiansheng Chen, Bo Huang

Although these methods differ essentially in many aspects, a common practice of them is to specifically align the facial area based on the prior knowledge of human face structure before feature extraction.
