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.

Interleaving One-Class and Weakly-Supervised Models with Adaptive Thresholding for Unsupervised Video Anomaly Detection

no code implementations24 Jan 2024 Yongwei Nie, Hao Huang, Chengjiang Long, Qing Zhang, Pradipta Maji, Hongmin Cai

In previous work, the two models are closely entangled with each other, and it is not known how to upgrade their method without modifying their training framework significantly.

Disentangled Representation Learning for Controllable Person Image Generation

no code implementations10 Dec 2023 Wenju Xu, Chengjiang Long, Yongwei Nie, Guanghui Wang

Unlike the existing works leveraging the semantic masks to obtain the representation of each component, we propose to generate disentangled latent code via a novel attribute encoder with transformers trained in a manner of curriculum learning from a relatively easy step to a gradually hard one.

Pyramid Texture Filtering

no code implementations11 May 2023 Qing Zhang, Hao Jiang, Yongwei Nie, Wei-Shi Zheng

We present a simple but effective technique to smooth out textures while preserving the prominent structures.

Fine-Grained Face Swapping via Regional GAN Inversion

no code implementations CVPR 2023 Zhian Liu, Maomao Li, Yong Zhang, Cairong Wang, Qi Zhang, Jue Wang, Yongwei Nie

We rethink face swapping from the perspective of fine-grained face editing, \textit{i. e., ``editing for swapping'' (E4S)}, and propose a framework that is based on the explicit disentanglement of the shape and texture of facial components.

Diverse Human Motion Prediction via Gumbel-Softmax Sampling from an Auxiliary Space

2 code implementations15 Jul 2022 Lingwei Dang, Yongwei Nie, Chengjiang Long, Qing Zhang, Guiqing Li

In this paper, we propose a novel sampling strategy for sampling very diverse results from an imbalanced multimodal distribution learned by a deep generative model.

Progressively Generating Better Initial Guesses Towards Next Stages for High-Quality Human Motion Prediction

1 code implementation CVPR 2022 Tiezheng Ma, Yongwei Nie, Chengjiang Long, Qing Zhang, Guiqing Li

This motivates us to propose a novel two-stage prediction framework, including an init-prediction network that just computes the good guess and then a formal-prediction network that predicts the target future poses based on the guess.

Dual Illumination Estimation for Robust Exposure Correction

2 code implementations30 Oct 2019 Qing Zhang, Yongwei Nie, Wei-Shi Zheng

By performing dual illumination estimation, we obtain two intermediate exposure correction results for the input image, with one fixes the underexposed regions and the other one restores the overexposed regions.

Enhancing Underexposed Photos using Perceptually Bidirectional Similarity

no code implementations25 Jul 2019 Qing Zhang, Yongwei Nie, Lei Zhu, Chunxia Xiao, Wei-Shi Zheng

To obtain high-quality results free of these artifacts, we present a novel underexposed photo enhancement approach that is able to maintain the perceptual consistency.

Understanding More about Human and Machine Attention in Deep Neural Networks

no code implementations20 Jun 2019 Qiuxia Lai, Salman Khan, Yongwei Nie, Jianbing Shen, Hanqiu Sun, Ling Shao

With three example computer vision tasks, diverse representative backbones, and famous architectures, corresponding real human gaze data, and systematically conducted large-scale quantitative studies, we quantify the consistency between artificial attention and human visual attention and offer novel insights into existing artificial attention mechanisms by giving preliminary answers to several key questions related to human and artificial attention mechanisms.
