A SAR Image Segment Method Using Gray Level Reduction Based on Graph in ICA Space被引量：5
《Chinese Journal of Electronics》2017年第4期883-888,共6页JI Jian LYU Xiaojia YAO Yafeng 
supported by the Fundamental Research Funds for the Central Universities of China(No.160302)
This paper proposes a new SAR image segmentation method based on graph and gray level reduction in Independent component analysis(ICA) space. Firstly,according to the grayscale information of SAR image, effective use ...

A Novel SAR Image Segmentation Method Using Run-Length Grouping被引量：2
《Chinese Journal of Electronics》2013年第2期396-400,共5页HU Lei JI Yan HOU Pengyang LI Bo 
This China （No.61262036）, the National Basic Research Program of for Distinguished Young Scholars （No.61125206）. work is partially supported by the National Natural Science Foundation of China （973 Program） （No.2010CB327900） and the National Science Fund
Synthetic aperture radar （SAR） image seg- mentation is the basis of SAR image analysis and under- standing. A segmentation method based on the neigh- bor and near spatial relationship is proposed to reduce the speck...

A Precise and Fast SAR Image Segmentation Method
《Chinese Journal of Electronics》2007年第3期471-475,共5页JU Yanwei TIAN Zheng ZHANG Yan 
This work is supported by the National Natural Science Foundation of China （No.60375003） and Aeronautics and Astronautics Basal Science Foundation of China （No.03153059）.
A Generalized multiresolution likelihood ratio （GMLR）, which can increases the distinction between different signals by fusing their more features, is defined. The GMLR for SAR （Synthetic aperture radar） image, th...

Multiscale MRF-based Texture Segmentation of SAR Image被引量：3
《Chinese Journal of Electronics》2004年第4期671-675,共5页XUXin LIDeren SUNHong 
We propose a multiscale Bayesian segmentation algorithm for SAR image in this paper. A hierarchical two-level Markov random field (MRF) is applied to represent both texture and region label over the wavelet lattice. T...
