Blockwise SVD with error in the operator and application to blind deconvolution
Blind deconvolution blockwise SVD circular and spherical deconvolution nonparametric adaptive estimation
2012/4/16
We consider linear inverse problems in a nonparametric statistical framework. Both the signal and the operator are unknown and subject to error measurements. We establish minimax rates of convergence ...
Application of speckle and (multi-object) multi-frame blind deconvolution techniques on imaging and imaging spectropolarimetric data
Sun: photosphere – Sun: spectropolarimeters
2011/9/27
We test the effects of reconstruction techniques on 2D data to determine the best approach. We obtained a time-series of spectropolarimetric data in the Fe I line at 630.25 nm with the Goettingen Fabr...
