Non-parameter Gibbs Model and Texture Segmentation of Multi-band Remote Sensing Image
-
摘要: 提出了一种新型的基于概率的非参数Gibbs模型,并建立了光谱空间-二维影像空间的映射关系,通过多级光谱编码策略实现了多波段遥感影像的纹理分割。Abstract: The texture model of multi-band remote sensing image based on Markov random field(MRF) is discussed,and the limitation of traditional Gibbs model is analyzed.A non-parameter Gibbs model is presented and a measure of multilevel-segmentation is taken.Based on this,an algorithm of multi-band remote sensing image texture segmentation is presented.
