Despeckling of Ultrasound Images Using Modified Local Statistics Mean Variance Filter
《Computer Modeling in Engineering & Sciences》2018年第1期19-32,共14页Ranu Gupta Rahul Pachauri Ashutosh Singh 
This article presents an improved method of despeckling the ultrasound medical images.In this paper a modified local statistics mean variance filter method has been proposed.In the proposed method,more consideration i...

GIS-Based Local Spatial Statistical Model of Cholera Occurrence: Using Geographically Weighted Regression被引量：1
《Journal of Geographic Information System》2013年第6期531-542,共12页Felix Ndidi Nkeki Animam Beecroft Osirike 
Global statistical techniques often assume homogeneity of relationships between dependent variable and predictors across space. This assumption has been criticized by statistical geographers as a fundamental weakness ...

A Convex Approach for Local Statistics Based Region Segmentation被引量：2
《Chinese Journal of Electronics》2012年第4期623-626,共4页MA Liyan YU Jian 
This work is supported by the National Natural Science Foundation of China （No.60905028, No.61033013） and Beijing Natural Science Foundation （No.4112046）.
A convex active contour model based on local image statistics is proposed in this paper. By assuming that the intensity distribution of the image pixels in a window is described by a Gaussian distribution, our model i...

Adaptive Noise Detection and Removal Algorithm Using Local Statistics for Salt-and-Pepper Noise
《Journal of Measurement Science and Instrumentation》2010年第4期323-325,共3页Tuan-anh NGUYEN Won-seon SONG Min-cheol HONG 
supported by the Korea Science and Engineering Foundation(KOSEF)granted bythe Korea government(MEST)(No.2009-0079776)
In this paper, an adaptive noise detection and removal algorithm using local statistics for salt-and-pepper noise are proposed. In order to determine constraints for noise detection, the local mean, varianoe, and maxi...

Local Environmental Dependence of Galaxy Properties in a Volume-Limited Sample of Main Galaxies
《Chinese Journal of Astronomy and Astrophysics》2007年第5期639-648,共10页Xin-Fa Deng Ji-Zhou He Qun Zhang Xiao-Xia Qian Peng Jiang Yong Xin 
Supported by the National Natural Science Foundation of China.
Using a volume-limited sample of Main Galaxies from SDSS Data Release 5, we investigate the dependence of galaxy properties on local environment. For each galaxy, a local three-dimensional density is calculated. We fi...
