The purpose of this paper is to compare and evaluate current spatial upscaling methods using MODIS remote sensing data with multiple spatial resolutions. In the research  Northeast China was selected as the study area. MODIS data with spatial resolutions of 250 m (2 bands) and 500 m (7 bands) were used as the test data. Through using the selected upscaling methods  the Band 1 and Band 2 data of MODIS were scaled up from 250 m to 500 m spatial resolution. On the basis of land cover characteristics of Northeast China  the MODIS data located in the study area was classified into the five land cover types  including water  grasslands  forests  farmlands and bare lands using maximum likelihood method. The land cover classification results were further compared with MODIS Land Cover Type product. Finally  Structural Similarity (SSIM) was selected to evaluate the effects of these upscaling methods. The research can provide more useful information for spatial scaling transformation in remote sensing data applications. 2012 SPIE.   Spatio-temporal patterns of intra-urban land use change in Beijing, China between 1984 and 2008 SCI/SSCI论文  OAI收割 2012 Kuang W.

The BP neural network is designed to fuse information of the two sensors to obtain the robot's environment model in this paper. The input of BP neural network is the intercept and slope of the edge line obtained CCD camera and ultrasonic sensor arrays  which is processed by through the global coordinates of coordinate transformation. The output of BP network is the fused intercept and slope of the straight edge. Experiment shows that environment model is feasible for the AS-R mobile robot and the environment modeling method has more reliability and accuracy. 2010 IEEE.   Parameter identification of airborne vibrated image based on high-speed CCD (EI CONFERENCE) 会议论文  OAI收割 2010 International Conference on Computer, Mechatronics, Control and Electronic Engineering, CMCE 2010, August 24, 2010 - August 26, 2010, Changchun, China Shi J.; Xue X.; Guo Y. 收藏  |  浏览/下载：36/0  |  提交时间：2013/03/25 In order to identify the vibration parameters of a vibrated image  the principle and shortage of the traditional methods that based on image derivative and image transformation are analyzed  and a new parameter identification method is proposed afterward. By placing a high-speed CCD aside the master CCD  the vibration can be sampled accurately  and more information can be obtained for parameter identification. The series frames that captured by high-speed CCD are processed by gray projection algorithm and the vibration extents between adjacent frames along x and y direction are obtained. By using simple triangle operations  the vibration parameters can be identified  and the computational complexity of which can be reduced greatly. The experiment shows that the parameter identification method based on high-speed CCD can identify the parameters of vibration with any form accurately. The precise of parameter identification for linear vibration is less than 2.95%. 2010 IEEE.   High-precise water extraction based on spectral-spatial coupled remote sensing information 会议论文  OAI收割 2010 IEEE International Geoscience and Remote Sensing Symposium, Toulouse, France, 2010 Luo; Jiancheng1; Sheng; Yongwei2; Shen; Zhanfeng1; Li; Junli3 收藏  |  浏览/下载：36/0  |  提交时间：2011/08/23 Geology - Information analysis - Remote sensing - Hierarchical knowledge - High-precise - Information Extraction - Iterative transformation - Local scale - Object oriented - Remote sensing applications - Remote sensing information - Remotely sensed images - Research fields - Spatial scale - Spectral angles - Spectral libraries - Step-by-step - Water bodies - Water extraction - Water index   Solitonic information transmission in general relativity 期刊论文  OAI收割 COMMUNICATIONS IN THEORETICAL PHYSICS, 2007, 卷号: 47, 期号: 4, 页码: 663-664 作者:  Shang Yu;  Wang Gui-Dong;  Wu Xiao-Ning;  Wang Shi-Kun;  Lau Yun-Kau   |  收藏  |  浏览/下载：20/0  |  提交时间：2018/07/30 Newman-Penrose tetrad  KdV wave  solitonic information transformation   a metamodel based model transformation approach 会议论文  OAI收割 3rd International Conference on Software Engineering Research, Management and Applications, Mt Pleasant, MI, AUG 11-13, Duan YC; Cheung SC; Fu XL; Gu YQ   |  收藏  |  浏览/下载：26/0  |  提交时间：2011/07/28 UML metamodel elements  information transformation problem  metamodel based model transformation approach  model driven software development  transformation rules  Unified Modeling Language  formal specification
