Monocular 3D Fingerprint Reconstruction and Unwarping

no code implementations2 May 2022 Zhe Cui, Jianjiang Feng, Jie zhou

Compared with contact-based fingerprint acquisition techniques, contactless acquisition has the advantages of less skin distortion, larger fingerprint area, and hygienic acquisition.

Bridge-Prompt: Towards Ordinal Action Understanding in Instructional Videos

1 code implementation CVPR 2022 Muheng Li, Lei Chen, Yueqi Duan, Zhilan Hu, Jianjiang Feng, Jie zhou, Jiwen Lu

The generated text prompts are paired with corresponding video clips, and together co-train the text encoder and the video encoder via a contrastive approach.

Meta-Mining Discriminative Samples for Kinship Verification

no code implementations CVPR 2021 Wanhua Li, Shiwei Wang, Jiwen Lu, Jianjiang Feng, Jie zhou

In the end, the samples in the unbalanced train batch are re-weighted by the learned meta-miner to optimize the kinship models.

GASNet: Weakly-supervised Framework for COVID-19 Lesion Segmentation

no code implementations19 Oct 2020 Zhanwei Xu, Yukun Cao, Cheng Jin, Guozhu Shao, Xiaoqing Liu, Jie zhou, Heshui Shi, Jianjiang Feng

Segmentation of infected areas in chest CT volumes is of great significance for further diagnosis and treatment of COVID-19 patients.

Semantics-Driven Unsupervised Learning for Monocular Depth and Ego-Motion Estimation

no code implementations8 Jun 2020 Xiaobin Wei, Jianjiang Feng, Jie zhou

In our method, we exploit semantic segmentation information to mitigate the effects of dynamic objects and occlusions in the scene, and to improve depth prediction performance by considering the correlation between depth and semantics.

Latent Fingerprint Registration via Matching Densely Sampled Points

no code implementations12 May 2020 Shan Gu, Jianjiang Feng, Jiwen Lu, Jie zhou

Given a pair of fingerprints to match, we bypass the minutiae extraction step and take uniformly sampled points as key points.

Graph-based Kinship Reasoning Network

no code implementations22 Apr 2020 Wanhua Li, Yingqiang Zhang, Kangchen Lv, Jiwen Lu, Jianjiang Feng, Jie zhou

In this paper, we propose a graph-based kinship reasoning (GKR) network for kinship verification, which aims to effectively perform relational reasoning on the extracted features of an image pair.

Dense Registration and Mosaicking of Fingerprints by Training an End-to-End Network

no code implementations13 Apr 2020 Zhe Cui, Jianjiang Feng, Jie zhou

In addition, based on the proposed registration algorithm, we propose a fingerprint mosaicking method based on optimal seam selection.

BridgeNet: A Continuity-Aware Probabilistic Network for Age Estimation

no code implementations CVPR 2019 Wanhua Li, Jiwen Lu, Jianjiang Feng, Chunjing Xu, Jie zhou, Qi Tian

Existing methods for age estimation usually apply a divide-and-conquer strategy to deal with heterogeneous data caused by the non-stationary aging process.

Correlated and Individual Multi-Modal Deep Learning for RGB-D Object Recognition

no code implementations6 Apr 2016 Ziyan Wang, Jiwen Lu, Ruogu Lin, Jianjiang Feng, Jie zhou

Specifically, we construct a pair of deep convolutional neural networks (CNNs) for the RGB and depth data, and concatenate them at the top layer of the network with a loss function which learns a new feature space where both correlated part and the individual part of the RGB-D information are well modelled.

Multiple Feature Fusion via Weighted Entropy for Visual Tracking

no code implementations ICCV 2015 Lin Ma, Jiwen Lu, Jianjiang Feng, Jie zhou

It is desirable to combine multiple feature descriptors to improve the visual tracking performance because different features can provide complementary information to describe objects of interest.
