马尔可夫随机场在SAR图像处理中的应用

旅游业是一种外向性特征鲜明、关联带动性强、可持续发展性强的产业。它对地方政府的招商引资工作有着独特而重要的促进作用:旅游项目本身是良好的引资项目;商务旅游的开发直接促进招商引资工作;旅游业的发展有助于塑造和改善地方形象,改善地方投资环境。要充分发挥这些积极作用,就应在商务旅游产品开发、旅游与招商工作相结合、城市建设与旅游开发一体化、旅游与相关产业相结合等方面多下功夫。

Markov Random Field Models for SAR Images Processing

By Selecting a proper neighborhood system and using the ability of Markov Random Field (MRF) to describe spatial dependence (continuity), MRF can be used to model the structural and textural behavior of images. Using the joint probability distribution in terms of an energy function, estimation of parameters can be performed by the stochastic relaxation algorithm. Gaussian MRF can represent a range of textures accurately and compactly and can be analysed tractably. In this paper,several MRF models are introduced, and the application of two models to restoration and segmentation of SAR images are presented in detail.
