基于马尔可夫随机场的遥感图像分割和描述

讨论了基于马尔可夫随机场的遥感图像分割．根据卫星遥感图像的特点,建立了相应的基于马尔可夫随机场的图像分割模型．由此将图像分割问题转化成图像标记问题, 并进一步转化成求图像的最大后验概率估计的问题． 本文引进了一种基于博弈理论的决定性退火算法, 可以用该算法对图像进行标记, 该算法收敛于局部最大, 在实验中取得了很好的效果．

Segmentation and Description of Satellite Image based on Markov Random Field

The segmentation of Remote Sensing Image based Markov Random Field (MRF) is discussed in this article. According to the characteristics of satellite image, a segmentation model based on MRF is established. Thus, the problem of segmentation is converted to the problem of image symbolizing, and finally converted to the solution of Maximum A Posterior(MAP). In this paper we provide a deterministic algorithm which is based on "Game Theory", use it to symbolize the image and prove that it can converge to a local optimum. Good result is got in the experiment.
