AN EFFICIENT METHOD TO CREATE DIGITAL TERRAIN MODELS FROM POINT CLOUDS COLLECTED BY MOBILE LiDAR SYSTEMS
Mobile systems point cloud Digital Terrain Models LiDAR Delaunay triangulation Laplacian operator
2017/7/12
The digital terrain models (DTM) assume an essential role in all types of road maintenance, water supply and sanitation projects. The demand of such information is more significant in developing count...
AN EFFICIENT METHOD FOR AUTOMATIC ROAD EXTRACTION BASED ON MULTIPLE FEATURES FROM LiDAR DATA
Remote sensing feature extraction pattern recognition LiDAR Road detection
2016/7/27
The road extraction in urban areas is difficult task due to the complicated patterns and many contextual objects. LiDAR data directly provides three dimensional (3D) points with less occlusions and sm...
An efficient method for large-scale gate sizing
Combinational logic circuits geometric process circuit
2015/8/10
We consider the problem of choosing the gate sizes or scale factors in a combinational logic circuit in order to minimize the total area, subject to simple RC timing constraints, and a minimum allowed...
An Efficient Method for Satellite Image Matching and Management
Image matching Wavelet transformation Satellite Image
2015/7/7
A method for matching two different images is discussed in this paper. Image matching is to match an image with other image that
may has different properties. In the matching, generally the images ar...
Mild and Highly Efficient Method for Synthesis of 14-Aryl(alkyl)- 14H-dibenzo[a,j]xanthenes and 1,8-Dioxooctahydroxanthene Derivatives Using Pentafluorophenyl Ammonium Triflate as a Novel Organocatalyst（图）
pentafluorophenyl ammonium triflate organocatalyst xanthene β-naphthol
2013/10/7
A simple and facile synthesis of 14-aryl and alkyl-14H-dibenzo[a,j]xanthenes and 1,8-dioxooctahydroxanthene derivatives has been successfully developed by treatment of β-naphthol or dimedone with alde...
An efficient method for human face recognition using nonsubsampled contourlet transform and support vector machine
multiscale geometric analysis face recognition
2011/5/10
To improve the recognition rate in different conditions, a multiscale face recognition method based on nonsubsampled contourlet transform and support vector machine is proposed in this paper. Firstly,...
