Local sparse representation for astronomical image denoisingYANG A-feng(杨阿锋), LU Min(鲁敏), TENG Shu-hua(滕书华), SUN Ji-xiang(孙即祥) (School of Electronic Science and Engineering, National University of Defense Technology, Changsha 410073, China)Abstract:Motivated by local coordinate coding (LCC) theory in nonlinear manifold learning, a new image representation model called local sparse representation......
samples before and after anneal was examined using spherical indentation at arranged testing points. It indicates that the scatter of the local strength measured by the Hertzian indentation is smaller in the anneal glass than in initial specimen, so that the estimated Weibull modulus for the anneal specimen is higher. Furthermore, the strength evaluation by Hertzian indentation and statistical......
