Center Contrastive Loss for Metric Learning

no code implementations1 Aug 2023 Bolun Cai, Pengfei Xiong, Shangxuan Tian

In this paper, we propose a novel metric learning function called Center Contrastive Loss, which maintains a class-wise center bank and compares the category centers with the query data points using a contrastive loss.

Both Spatial and Frequency Cues Contribute to High-Fidelity Image Inpainting

no code implementations15 Jul 2023 Ze Lu, Yalei Lv, Wenqi Wang, Pengfei Xiong

Specifically, we introduce an extra Frequency Branch and Frequency Loss on the spatial-based network to impose direct supervision on the frequency information, and propose a Frequency-Spatial Cross-Attention Block (FSCAB) to fuse multi-domain features and combine the corresponding characteristics.

Video-Text as Game Players: Hierarchical Banzhaf Interaction for Cross-Modal Representation Learning

4 code implementations CVPR 2023 Peng Jin, Jinfa Huang, Pengfei Xiong, Shangxuan Tian, Chang Liu, Xiangyang Ji, Li Yuan, Jie Chen

Contrastive learning-based video-language representation learning approaches, e. g., CLIP, have achieved outstanding performance, which pursue semantic interaction upon pre-defined video-text pairs.

RepGhost: A Hardware-Efficient Ghost Module via Re-parameterization

2 code implementations11 Nov 2022 Chengpeng Chen, Zichao Guo, Haien Zeng, Pengfei Xiong, Jian Dong

Experiments on ImageNet and COCO benchmarks demonstrate that the proposed RepGhostNet is much more effective and efficient than GhostNet and MobileNetV3 on mobile devices.

TS2-Net: Token Shift and Selection Transformer for Text-Video Retrieval

1 code implementation16 Jul 2022 Yuqi Liu, Pengfei Xiong, Luhui Xu, Shengming Cao, Qin Jin

In this paper, we propose Token Shift and Selection Network (TS2-Net), a novel token shift and selection transformer architecture, which dynamically adjusts the token sequence and selects informative tokens in both temporal and spatial dimensions from input video samples.

Aesthetic Text Logo Synthesis via Content-aware Layout Inferring

1 code implementation CVPR 2022 Yizhi Wang, Guo Pu, Wenhan Luo, Yexin Wang, Pengfei Xiong, Hongwen Kang, Zhouhui Lian

To train and evaluate our approach, we construct a dataset named as TextLogo3K, consisting of about 3, 500 text logo images and their pixel-level annotations.

CLIP2Video: Mastering Video-Text Retrieval via Image CLIP

1 code implementation21 Jun 2021 Han Fang, Pengfei Xiong, Luhui Xu, Yu Chen

We present CLIP2Video network to transfer the image-language pre-training model to video-text retrieval in an end-to-end manner.

Local Context Attention for Salient Object Segmentation

no code implementations24 Sep 2020 Jing Tan, Pengfei Xiong, Yuwen He, Kuntao Xiao, Zhengyi Lv

Based on this priori, we propose a novel Local Context Attention Network (LCANet) to generate locally reinforcement feature maps in a uniform representational architecture.

TP-LSD: Tri-Points Based Line Segment Detector

2 code implementations ECCV 2020 Siyu Huang, Fangbo Qin, Pengfei Xiong, Ning Ding, Yijia He, Xiao Liu

To realize one-step detection with a faster and more compact model, we introduce the tri-points representation, converting the line segment detection to the end-to-end prediction of a root-point and two endpoints for each line segment.

Affinity-aware Compression and Expansion Network for Human Parsing

no code implementations24 Aug 2020 Xinyan Zhang, Yunfeng Wang, Pengfei Xiong

As a fine-grained segmentation task, human parsing is still faced with two challenges: inter-part indistinction and intra-part inconsistency, due to the ambiguous definitions and confusing relationships between similar human parts.

Deep Fusion Network for Image Completion

5 code implementations17 Apr 2019 Xin Hong, Pengfei Xiong, Renhe Ji, Haoqiang Fan

The fusion block not only provides a smooth fusion between restored and existing content, but also provides an attention map to make network focus more on the unknown pixels.
