Human-to-Human Interaction Detection

no code implementations2 Jul 2023 Zhenhua Wang, Kaining Ying, Jiajun Meng, Jifeng Ning

First, based on the popular AVA dataset created for action detection, we establish a new HID benchmark, termed AVA-Interaction (AVA-I), by adding annotations on interactive relations in a frame-by-frame manner.

BoPR: Body-aware Part Regressor for Human Shape and Pose Estimation

1 code implementation21 Mar 2023 Yongkang Cheng, Shaoli Huang, Jifeng Ning, Ying Shan

This paper presents a novel approach for estimating human body shape and pose from monocular images that effectively addresses the challenges of occlusions and depth ambiguity.

Geometric Structure Preserving Warp for Natural Image Stitching

1 code implementation CVPR 2022 Peng Du, Jifeng Ning, Jiguang Cui, Shaoli Huang, Xinchao Wang, Jiaxin Wang

Further, an optimized GES energy term is presented to reasonably determine the weights of the sampling points on the geometric structure, and the term is added into the Global Similarity Prior (GSP) stitching model called GES-GSP to achieve a smooth transition between local alignment and geometric structure preservation.

Hyperspectral Image Denoising via Global Spatial-Spectral Total Variation Regularized Nonconvex Local Low-Rank Tensor Approximation

no code implementations30 May 2020 Haijin Zeng, Xiaozhen Xie, Jifeng Ning

Instead of traditional bandwise total variation, we use the SSTV regularization to simultaneously consider global spatial structure and spectral correlation of neighboring bands.

Enhanced nonconvex low-rank approximation of tensor multi-modes for tensor completion

no code implementations28 May 2020 Haijin Zeng, Xiaozhen Xie, Jifeng Ning

Higher-order low-rank tensor arises in many data processing applications and has attracted great interests.

Hyperspectral Image Restoration via Global Total Variation Regularized Local nonconvex Low-Rank matrix Approximation

no code implementations8 May 2020 Haijin Zeng, Xiaozhen Xie, Jifeng Ning

From one aspect, local LR of HSIs is formulated using a non-convex $L_{\gamma}$-norm, which provides a closer approximation to the matrix rank than the traditional NN.

Tensor completion using enhanced multiple modes low-rank prior and total variation

no code implementations19 Apr 2020 Haijin Zeng, Xiaozhen Xie, Jifeng Ning

In this paper, we propose a novel model to recover a low-rank tensor by simultaneously performing double nuclear norm regularized low-rank matrix factorizations to the all-mode matricizations of the underlying tensor.

Object Tracking via Dual Linear Structured SVM and Explicit Feature Map

no code implementations CVPR 2016 Jifeng Ning, Jimei Yang, Shaojie Jiang, Lei Zhang, Ming-Hsuan Yang

Structured support vector machine (SSVM) based methods has demonstrated encouraging performance in recent object tracking benchmarks.
