A simple but efficient algorithm for multiple-image deblurring
R. Vio, J. Nagy, L. Tenorio +1
We consider the simultaneous deblurring of a set of noisy images whose point spread functions are different but known and spatially invariant, and the noise is Gaussian. Currently…
Digital Deblurring of CMB Maps II: Asymmetric Point Spread Function
R. Vio, J. G. Nagy, L. Tenorio +3
In this second paper in a series dedicated to developing efficient numerical techniques for the deblurring Cosmic Microwave Background (CMB) maps, we consider the case of asymmetri…
Some Good Reasons to Use Matched Filters for the Detection of Point Sources in CMB Maps
Roberto Vio, Paola Andreani, Willelm Wamsteker
In this draft we comment on the results concerning the performances of matched filters, scale adaptive filters and Mexican hat wavelet that recently appeared in literature in the c…
Digital Deblurring of CMB Maps: Performance and Efficient Implementation
R. Vio, J. G. Nagy, L. Tenorio +3
Digital deblurring of images is an important problem that arises in multifrequency observations of the Cosmic Microwave Background (CMB) where, because of the width of the point sp…
