Boosting Long-tailed Object Detection via Step-wise Learning on Smooth-tail Data

no code implementations ICCV 2023 Na Dong, Yongqiang Zhang, Mingli Ding, Gim Hee Lee

Real-world data tends to follow a long-tailed distribution, where the class imbalance results in dominance of the head classes during training.

Towards Unbiased Volume Rendering of Neural Implicit Surfaces With Geometry Priors

no code implementations CVPR 2023 Yongqiang Zhang, Zhipeng Hu, Haoqian Wu, Minda Zhao, Lincheng Li, Zhengxia Zou, Changjie Fan

In this paper, we argue that this limited accuracy is due to the bias of their volume rendering strategies, especially when the viewing direction is close to be tangent to the surface.

Open World DETR: Transformer based Open World Object Detection

no code implementations6 Dec 2022 Na Dong, Yongqiang Zhang, Mingli Ding, Gim Hee Lee

Open world object detection aims at detecting objects that are absent in the object classes of the training data as unknown objects without explicit supervision.

Incremental-DETR: Incremental Few-Shot Object Detection via Self-Supervised Learning

no code implementations9 May 2022 Na Dong, Yongqiang Zhang, Mingli Ding, Gim Hee Lee

Incremental few-shot object detection aims at detecting novel classes without forgetting knowledge of the base classes with only a few labeled training data from the novel classes.

Bridging Non Co-occurrence with Unlabeled In-the-wild Data for Incremental Object Detection

1 code implementation NeurIPS 2021 Na Dong, Yongqiang Zhang, Mingli Ding, Gim Hee Lee

In view of this limitation, we consider a more practical setting of complete absence of co-occurrence of the base and novel classes for the object detection task.

Performance Analysis and Optimization of Cooperative Satellite-Aerial-Terrestrial Systems

no code implementations21 Jun 2020 Gaofeng Pan, Jia Ye, Yongqiang Zhang, Mohamed-Slim Alouini

Aerial relays have been regarded as an alternative and promising solution to extend and improve satellite-terrestrial communications, as the probability of line-of-sight transmissions increases compared with adopting terrestrial relays.

SOD-MTGAN: Small Object Detection via Multi-Task Generative Adversarial Network

no code implementations ECCV 2018 Yancheng Bai, Yongqiang Zhang, Mingli Ding, Bernard Ghanem

In the MTGAN, the generator is a super-resolution network, which can up-sample small blurred images into fine-scale ones and recover detailed information for more accurate detection.

Finding Tiny Faces in the Wild With Generative Adversarial Network

no code implementations CVPR 2018 Yancheng Bai, Yongqiang Zhang, Mingli Ding, Bernard Ghanem

In this paper, we proposed an algorithm to directly generate a clear high-resolution face from a blurry small one by adopting a generative adversarial network (GAN).
