摘要: 提出广义多分辨似然比(generalized multiresolution likelihood ratio,简称GMLR)的概念,给出其Bayes准则下的假设检验和判别准则。GMLR不仅能融合信号的多个特征量,增大不同信号间区分度,而且在融合时无需假定各特征量之间的相互关系,这使得它能进行比较精确而方便的判别分析。在SAR(synthetic aperture radar)图像分割应用背景中,利用混合多尺度自回归预报(mixture multiscale autoregressive predicti

Abstract: A generalized multiresolution likelihood ratio (GMLR) is defined, then the GMI.R test is obtained. The GMLR has the characteristic that can fuse several features which describe different properties, and it can increase distinction between different source

Key words: Generalized multiresolution likelihood ratio (GMLR), Unsupervised segmentation, Mixture multiscale au toregressive prediction (MMARP) model, Precise
