50 Years of Image Processing and Pattern Recognition in China
Found in: IEEE Intelligent Systems
By Nanning Zheng, Qubo You, Gaofeng Meng, Jihua Zhu, Shaoyi Du, Jianyi Liu
Issue Date:November 2008
pp. 33-41
This article briefly reviews the development of image recognition in and outside China. It presents theoretical research achievements and applied research as well as several typical applications of image recognition in China. Finally, it discusses future t...
 
Efficient Image Dehazing with Boundary Constraint and Contextual Regularization
Found in: 2013 IEEE International Conference on Computer Vision (ICCV)
By Gaofeng Meng,Ying Wang,Jiangyong Duan,Shiming Xiang,Chunhong Pan
Issue Date:December 2013
pp. 617-624
Images captured in foggy weather conditions often suffer from bad visibility. In this paper, we propose an efficient regularization method to remove hazes from a single input image. Our method benefits much from an exploration on the inherent boundary cons...
 
Nonparametric Illumination Correction for Scanned Document Images via Convex Hulls
Found in: IEEE Transactions on Pattern Analysis and Machine Intelligence
By Gaofeng Meng, Shiming Xiang, Nanning Zheng, Chunhong Pan
Issue Date:July 2013
pp. 1730-1743
A scanned image of an opened book page often suffers from various scanning artifacts known as scanning shading and dark borders noises. These artifacts will degrade the qualities of the scanned images and cause many problems to the subsequent process of do...
 
Metric Rectification of Curved Document Images
Found in: IEEE Transactions on Pattern Analysis and Machine Intelligence
By Gaofeng Meng,Chunhong Pan,Shiming Xiang,Jiangyong Duan
Issue Date:April 2012
pp. 707-722
In this paper, we propose a metric rectification method to restore an image from a single camera-captured document image. The core idea is to construct an isometric image mesh by exploiting the geometry of page surface and camera. Our method uses a general...
 
Guided tone mapping
Found in: ACM SIGGRAPH 2012 Posters (SIGGRAPH '12)
By Chunhong Pan, Gaofeng Meng, Huxiang Gu, Shiming Xiang, Ying Wang
Issue Date:August 2012
pp. 1-1
In this paper, we propose a simple but effective tone mapping operator, which can achieve impressive results with low complexity in both the formulation and computation. The key point of our operator is to calculate a scalar matrix by which the input HDR i...
