The ever-increasing gigantic amount of images over the web necessitates automatic schemes for meta-tagging content descriptions such as object categories. These meta-tags are essential to text-based...
Face Re-Lighting from a Single Image under Harsh Lighting Conditions (2008)
Yang Wang, Zicheng Liu, Gang Hua, Zhen Wen, Zhengyou Zhang, Dimitris Samaras
In this paper, we present a new method to change the illumination condition of a face image, with unknown face geometry and albedo information. This problem is particularly difficult when there is...
Variational Maximum A Posteriori by Annealed Mean Field Analysis (2008)
Gang Hua, Student Member, Ying Wu
Abstract—This paper proposes a novel probabilistic variational method with deterministic annealing for the maximum a posteriori (MAP) estimation of complex stochastic systems. Since the MAP...
{ganghua, yingwu} @ ece.northwestern.edu In this paper, we propose a novel sequential variational maximum a posteriori (MAP) algorithm to recover the articulated human body motion from video for...

AUTOMATIC BUSINESS CARD SCANNING WITH A CAMERA (2008)
Gang Hua, Zicheng Liu, Zhengyou Zhang, Ying Wu
In this paper, we present a system to automatically extract, rectify and enhance business card images. First the business card image patch is automatically segmented by minimizing a novel...
Spatial Sparsity Induced Temporal Prediction for Hybrid Video Compression (2007)
In this paper we propose a new motion compensated prediction technique that enables successful predictive encoding during fades, blended scenes, temporally decorrelated noise, and many other temporal...
Measurement integration under inconsistency for robust tracking (2006)
The solutions to many vision problems involve integrating measurements from multiple sources. Most existing methods rely on a hidden assumption, i.e., these measurements are consistent. In reality,...
Noncoherent image denoising (2005)
The techniques of Translation Invariant (TI) denoising and statistical modeling are widely used in image denoising. This thesis studies how these techniques exploit location information in images and...
Learning to estimate human pose with data driven belief propagation (2005)
Gang Hua, Ming-hsuan Yang, Ying Wu
We propose a statistical formulation for 2-D human pose estimation from single images. The human body configuration is modeled by a Markov network and the estimation problem is to infer pose...
Efficient optimal kernel placement for reliable visual tracking (2005)
Zhimin Fan, Ming Yang, Ying Wu, Gang Hua, Ting Yu
This paper describes a novel approach to optimal kernel placement in kernel-based tracking. If kernels are placed at arbitrary places, kernel-based methods are likely to be trapped in ill-conditioned...

Hua, Gang, Masson, Luke, Jurat-Fuentes, Juan Luis, Schwab, George, Adang, Michael J.
Transgenic corn expressing the Bacillus thuringiensis Cry1Ab gene is highly insecticidal to Ostrinia nubilalis (European corn borer) larvae. We ascertained whether Cry1F, Cry9C, or Cry9E recognizes...

Synergism of Bacillus thuringiensis toxins by a fragment of a toxin-binding cadherin
Chen, Jiang, Hua, Gang, Jurat-Fuentes, Juan Luis, Abdullah, Mohd Amir, Adang, Michael J.
The insecticidal crystal proteins produced by Bacillus thuringiensis (Bt) are broadly used to control insect pests with agricultural importance. The cadherin Bt-R1 is a binding protein for Bt Cry1A...
