Accurate Range Image Registration: Eliminating or Modelling Outliers

Li, Longzhuang; Liu, Honghai; Wei, Baogang; Liu, Yonghuai (2007-09)

Automatic and accurate range image registration is often a prerequisite step for range image analysis and interpretation. Due to occlusion, appearance and disappearance of points in different images, outliers inevitably ...
A Clustering Approach to Free Form Surface Reconstruction from Multi-view Range Images

Zhou, Hong; Liu, Yonghuai; Li, Longzhuang; Wei, Baogang (2011-11-08)

3D modelling finds a wide range of applications in robot vision and reverse engineering. However due to the presence of surface scanning noise, accumulative registration errors, and improper data fusion, the reconstructed ...
Using hybrid knowledge engineering and image processing in color virtual restoration of ancient murals

Pan, Yunhe; Liu, Yonghuai; Wei, Baogang (2003-09)

Abstract—This paper proposes a novel scheme to virtually restore the colors of ancient murals. Our approach integrates artificial intelligence techniques with digital image processing methods. The knowledge related to the ...
