Bidirectional Feature Pyramid Network with Recurrent Attention Residual Modules for Shadow Detection

1 code implementation ECCV 2018 Lei Zhu, Zijun Deng, Xiao-Wei Hu, Chi-Wing Fu, Xuemiao Xu, Jing Qin, Pheng-Ann Heng

Second, we develop a bidirectional feature pyramid network (BFPN) to aggregate shadow contexts spanned across different CNN layers by deploying two series of RAR modules in the network to iteratively combine and refine context features: one series to refine context features from deep to shallow layers, and another series from shallow to deep layers.

Context-aware and Scale-insensitive Temporal Repetition Counting

1 code implementation CVPR 2020 Huaidong Zhang, Xuemiao Xu, Guoqiang Han, Shengfeng He

It avoids the heavy computation of exhaustively searching all the cycle lengths in the video, and, instead, it propagates the coarse prediction for further refinement in a hierarchical manner.

From Continuity to Editability: Inverting GANs with Consecutive Images

2 code implementations ICCV 2021 Yangyang Xu, Yong Du, Wenpeng Xiao, Xuemiao Xu, Shengfeng He

This inborn property is used for two unique purposes: 1) regularizing the joint inversion process, such that each of the inverted code is semantically accessible from one of the other and fastened in a editable domain; 2) enforcing inter-image coherence, such that the fidelity of each inverted code can be maximized with the complement of other images.

Where Is My Spot? Few-Shot Image Generation via Latent Subspace Optimization

1 code implementation CVPR 2023 Chenxi Zheng, Bangzhen Liu, Huaidong Zhang, Xuemiao Xu, Shengfeng He

The rationale behind is that we aim to locate a centroid latent position in a conditional StyleGAN, where the corresponding output image on that centroid can maximize the similarity with the given samples.

BroadCAM: Outcome-agnostic Class Activation Mapping for Small-scale Weakly Supervised Applications

1 code implementation7 Sep 2023 Jiatai Lin, Guoqiang Han, Xuemiao Xu, Changhong Liang, Tien-Tsin Wong, C. L. Philip Chen, Zaiyi Liu, Chu Han

Class activation mapping~(CAM), a visualization technique for interpreting deep learning models, is now commonly used for weakly supervised semantic segmentation~(WSSS) and object localization~(WSOL).

DLFormer: Discrete Latent Transformer for Video Inpainting

no code implementations CVPR 2022 Jingjing Ren, Qingqing Zheng, YuanYuan Zhao, Xuemiao Xu, Chen Li

Video inpainting remains a challenging problem to fill with plausible and coherent content in unknown areas in video frames despite the prevalence of data-driven methods.

Towards a Smaller Student: Capacity Dynamic Distillation for Efficient Image Retrieval

no code implementations CVPR 2023 Yi Xie, Huaidong Zhang, Xuemiao Xu, Jianqing Zhu, Shengfeng He

Specifically, the employed student model is initially a heavy model to fruitfully learn distilled knowledge in the early training epochs, and the student model is gradually compressed during the training.

Incorporating Exemplar Optimization into Training with Dual Networks for Human Mesh Recovery

no code implementations25 Jan 2024 Yongwei Nie, Mingxian Fan, Chengjiang Long, Qing Zhang, Jian Zhu, Xuemiao Xu

(2) We devise a dual-network architecture to convey the novel training paradigm, which is composed of a main regression network and an auxiliary network, in which we can formulate the exemplar optimization loss function in the same form as the training loss function.
