Per-pixel translational symmetry detection, optimization, and segmentation
Found in: 2012 IEEE Conference on Computer Vision and Pattern Recognition (CVPR)
By Peng Zhao, Lei Yang, Honghui Zhang, Long Quan
Issue Date:June 2012
pp. 526-533
We present a novel method for translational symmetry detection, optimization, and symmetry object segmentation in façade images. Unlike most previous methods, our detection algorithm accumulates pixel-level correspondence in translation space. Thus it does...
 
Learning CRFs for Image Parsing with Adaptive Subgradient Descent
Found in: 2013 IEEE International Conference on Computer Vision (ICCV)
By Honghui Zhang,Jingdong Wang,Ping Tan,Jinglu Wang,Long Quan
Issue Date:December 2013
pp. 3080-3087
We propose an adaptive sub gradient descent method to efficiently learn the parameters of CRF models for image parsing. To balance the learning efficiency and performance of the learned CRF models, the parameter learning is iteratively carried out by solvi...
 
Image-Based Modeling of Unwrappable Façades
Found in: IEEE Transactions on Visualization and Computer Graphics
By Tian Fang, Zhexi Wang, Honghui Zhang, Long Quan
Issue Date:October 2013
pp. 1720-1731
In this paper, we propose an unwrappable representation for image-based façade modeling from multiple registered images. An unwrappable façade is represented by the mutually orthogonal baseline and profile. We first reconstruct semidense 3D points from ima...
 
Partial similarity based nonparametric scene parsing in certain environment
Found in: Computer Vision and Pattern Recognition, IEEE Computer Society Conference on
By Honghui Zhang, Tian Fang, Xiaowu Chen, Qinping Zhao, Long Quan
Issue Date:June 2011
pp. 2241-2248
In this paper we propose a novel nonparametric image parsing method for the image parsing problem in certain environment. A novel and efficient nearest neighbor matching scheme, the ANN bilateral matching scheme, is proposed. Based on the proposed matching...
 
Rectilinear parsing of architecture in urban environment
Found in: Computer Vision and Pattern Recognition, IEEE Computer Society Conference on
By Peng Zhao, Tian Fang, Jianxiong Xiao, Honghui Zhang, Qinping Zhao, Long Quan
Issue Date:June 2010
pp. 342-349
We propose an approach that parses registered images captured at ground level into architectural units for large-scale city modeling. Each parsed unit has a regularized shape, which can be used for further modeling purposes. In our approach, we first parse...
 
Pose Parameter Estimation and Shape Distance
Found in: Computer Science and Software Engineering, International Conference on
By Yong Tan, Honghui Zhang, Dongkun Xia
Issue Date:December 2008
pp. 899-902
In this paper, a pose parameter estimation method is proposed, which provides an effective solution for the local optimal pose parameters problem in the shape distance measurements based on various level set based shape distance energy functions. To acquir...
 
A Transformation Method of Scenarios from Different Viewpoints
Found in: Asia-Pacific Software Engineering Conference
By Honghui Zhang, Atsushi Ohnishi
Issue Date:December 2004
pp. 492-501
Scenarios that describe concrete situations of software operation play an important role in software development and especially in requirements engineering. Scenario details should vary in content when described from different viewpoints, but this presents...
