Online selection of discriminative tracking features

RT Collins, Y Liu, M Leordeanu - IEEE transactions on pattern …, 2005 - ieeexplore.ieee.org
This paper presents an online feature selection mechanism for evaluating multiple features
while tracking and adjusting the set of features used to improve tracking performance. Our …

Effects of low-carbohydrate and low-fat diets: a randomized trial

…, T Hu, K Reynolds, L Yao, C Bunol, Y Liu… - Annals of internal …, 2014 - acpjournals.org
Background: Low-carbohydrate diets are popular for weight loss, but their cardiovascular
effects have not been well-studied, particularly in diverse populations. Objective: To examine …

A computational model for periodic pattern perception based on frieze and wallpaper groups

Y Liu, RT Collins, Y Tsin - IEEE transactions on pattern analysis …, 2004 - ieeexplore.ieee.org
We present a computational model for periodic pattern perception based on the mathematical
theory of crystallographic groups. In each N-dimensional Euclidean space, a finite number …

Near-regular texture analysis and manipulation

Y Liu, WC Lin, J Hays - ACM Transactions on Graphics (ToG), 2004 - dl.acm.org
A near-regular texture deviates geometrically and photometrically from a regular congruent
tiling. Although near-regular textures are ubiquitous in the man-made and natural world, they …

Robust midsagittal plane extraction from normal and pathological 3-D neuroradiology images

Y Liu, RT Collins, WE Rothfus - IEEE transactions on medical …, 2001 - ieeexplore.ieee.org
This paper focuses on extracting the ideal midsagittal plane (iMSP) from three-dimensional (3-D)
normal and pathological neuroimages. The main challenges in this work are the …

Computational symmetry in computer vision and computer graphics

Y Liu, H Hel-Or, CS Kaplan… - Foundations and Trends …, 2010 - nowpublishers.com
In the arts and sciences, as well as in our daily lives, symmetry has made a profound and
lasting impact. Likewise, a computational treatment of symmetry and group theory (the ultimate …

Atlas-based hippocampus segmentation in Alzheimer's disease and mild cognitive impairment

…, JT Becker, PM Thompson, CC Meltzer, Y Liu - Neuroimage, 2005 - Elsevier
This study assesses the performance of public-domain automated methodologies for MRI-based
segmentation of the hippocampus in elderly subjects with Alzheimer's disease (AD) and …

Strategies for articular cartilage repair and regeneration

Y Liu, KM Shah, J Luo - Frontiers in Bioengineering and …, 2021 - frontiersin.org
Articular cartilage is an avascular tissue, with limited ability to repair and self-renew. Defects
in articular cartilage can induce debilitating degenerative joint diseases such as …

Association of C-reactive protein, tumor necrosis factor-alpha, and interleukin-6 with chronic kidney disease

…, FA Ahmed, LL Hamm, FJ Teran, CS Chen, Y Liu… - BMC nephrology, 2015 - Springer
Background We studied the association of inflammatory biomarkers including C-reactive
protein (CRP), tumor necrosis factor-alpha (TNF-α), and interleukin-6 (IL-6) with chronic kidney …

Gait sequence analysis using frieze patterns

Y Liu, R Collins, Y Tsin - European Conference on Computer Vision, 2002 - Springer
We analyze walking people using a gait sequence representation that bypasses the need
for frame-to-frame tracking of body parts. The gait representation maps a video sequence of …
