提出了一种新的MSTAR SAR图像分割方法。该方法首先根据地物的散射机制进行属性散射中心(attributed scattering centers,ASC)特征提取,构造属性散射中心特征向量;然后使用马尔科夫随机场(Markov random field,MRF)结合属性散射中心特征对MSTAR SAR图像进行空间邻域关系描述;最后运用标号代价能量优化算法得到最终的分割结果。MSTAR SAR
Silicon nitride composite is joined to itself by heating interlayer of Y2O3-Al2O3-SiO2 mixtures above their liquidus temperatures in flowing nitrogen. The joine
It was reported that TiB2 gains grew fast during sintering was a main cause for its properties degrading.In this paper the HP-sintering mechanics of TiB2 was st
