Hyperspectral imagery provides more powerful information than multispectral remote sensing data. However, when hyperspectral data is used for classification task, the highdimension features often lead to ill-conditioned problems, such as the Hughes phenomenon. To tackle this problem, various supervised dimensional reduction methods are proposed. However, these methods only exploit the labeled training...
Speckle imaging technique is one of the several effective approaches, which can overcome atmosphere turbulence effects to improve resolution power of the ground-based telescope. It has been widely used in the astronomical observation research. The observation experiments using this technique have been made on 1.56-m telescope with an EMCCD speckle camera at SHAO. Results are presented from a series...
