基于MRF模型的SAR图像变化检测研究
A Study on SAR Image Change Detection Based on Markov Random Field Models
摘要
Abstract
As one of the hot topic fields,SAR image change detection can be applied to many fields of economy and defense construction.The information of only one pixel is considered by existing algorithms of SAR image change detection,but the spatial correction within the neighbouring pixels of image is not considered,so the results of detection are sensitive to image noise and the detection accuracy is very low.The detection algorithm based on MRF model,which the dependency relationship among pixels of image can be discribed and the local statistical characteristics of image is proposed.The results of experiments show that the detection accuracy of the algorithm proposed in this paper is very high and the detection result has very high robust to image noise.关键词
