From Image to Stability: Learning Dynamics from Human Pose

no code implementations ECCV 2020 Jesse Scott, Bharadwaj Ravichandran, Christopher Funk, Robert T. Collins, Yanxi Liu

We propose and validate two end-to-end deep learning architectures to learn foot pressure distribution maps (dynamics) from 2D or 3D human pose (kinematics).

EscherNet 101

no code implementations7 Mar 2023 Christopher Funk, Yanxi Liu

A deep learning model, EscherNet 101, is constructed to categorize images of 2D periodic patterns into their respective 17 wallpaper groups.

Stock Market Prediction via Deep Learning Techniques: A Survey

no code implementations24 Dec 2022 Jinan Zou, Qingying Zhao, Yang Jiao, Haiyao Cao, Yanxi Liu, Qingsen Yan, Ehsan Abbasnejad, Lingqiao Liu, Javen Qinfeng Shi

Existing surveys on stock market prediction often focus on traditional machine learning methods instead of deep learning methods.

Novel 3D Scene Understanding Applications From Recurrence in a Single Image

no code implementations14 Oct 2022 Shimian Zhang, Skanda Bharadwaj, Keaton Kraiger, Yashasvi Asthana, Hong Zhang, Robert Collins, Yanxi Liu

We demonstrate the utility of recurring pattern discovery from a single image for spatial understanding of a 3D scene in terms of (1) vanishing point detection, (2) hypothesizing 3D translation symmetry and (3) counting the number of RP instances in the image.

Image-based Stability Quantification

no code implementations23 Jun 2022 Jesse Scott, John Challis, Robert T. Collins, Yanxi Liu

Quantitative evaluation of human stability using foot pressure/force measurement hardware and motion capture (mocap) technology is expensive, time consuming, and restricted to the laboratory.

From Kinematics To Dynamics: Estimating Center of Pressure and Base of Support from Video Frames of Human Motion

no code implementations2 Jan 2020 Jesse Scott, Christopher Funk, Bharadwaj Ravichandran, John H. Challis, Robert T. Collins, Yanxi Liu

To gain an understanding of the relation between a given human pose image and the corresponding physical foot pressure of the human subject, we propose and validate two end-to-end deep learning architectures, PressNet and PressNet-Simple, to regress foot pressure heatmaps (dynamics) from 2D human pose (kinematics) derived from a video frame.

Beyond Planar Symmetry: Modeling human perception of reflection and rotation symmetries in the wild

no code implementations ICCV 2017 Christopher Funk, Yanxi Liu

Humans take advantage of real world symmetries for various tasks, yet capturing their superb symmetry perception mechanism with a computational model remains elusive.

Regularity-Driven Facade Matching Between Aerial and Street Views

no code implementations CVPR 2016 Mark Wolff, Robert T. Collins, Yanxi Liu

We present an approach for detecting and matching building facades between aerial view and street-view images.

Symmetry reCAPTCHA

no code implementations CVPR 2016 Chris Funk, Yanxi Liu

This is a reaction to the poor performance of symmetry detection algorithms on real-world images, benchmarked since CVPR 2011.

Local Regularity-driven City-scale Facade Detection from Aerial Images

no code implementations CVPR 2014 Jingchen Liu, Yanxi Liu

We propose a novel regularity-driven framework for facade detection from aerial images of urban scenes.

GRASP Recurring Patterns from a Single View

no code implementations CVPR 2013 Jingchen Liu, Yanxi Liu

We propose a novel unsupervised method for discovering recurring patterns from a single view.

Tracking Sports Players with Context-Conditioned Motion Models

no code implementations CVPR 2013 Jingchen Liu, Peter Carr, Robert T. Collins, Yanxi Liu

Instead, we introduce a set of Game Context Features extracted from noisy detections to describe the current state of the match, such as how the players are spatially distributed.

Texture replacement in real images

no code implementations CVPR 2001 Yanghai Tsin, Yanxi Liu, V. Ramesh

To achieve convincing replacement results we have to detect texture patterns and estimate the lighting map from a given image.
