In this paper, a novel image registration method, called ensemble image registration, is proposed. We use an infinite Gaussian mixture model (IGMM), which is based on a joint Gaussian mixture model and a Dirichlet process (DP), to model the joint intensity scatter plot (JISP) of the unregistered images. The DP is the cornerstone of nonparametric Bayesian statistics, and has capability of determining...
The fiber Bragg grating has been written in a novel high birefringence (Hi-Bi) fiber by phase-mask method. The temperature and gas pressure characteristics of the fiber Bragg grating were analyzed and demonstrated quantitatively. Two Bragg wavelengths corresponding to the fast-axis mode and slow-axis mode shift linearly with temperature change and gas pressure change. Experimental results showed that...
