We continue the study of list recovery properties of high-rate tensor codes, initiated by Hemenway, and Wootters (FOCS'17). ...
This bound implies in turn a nearly-tight lower bound of N Ω(1/ log log N ) on the product of query complexity and output list size for locally list recovering high-rate tensor codes. ...

In this work a joint alternating recovery of the high-resolution image and of the unknown point spread function parameters is proposed. The method is evaluated on dental computed tomography images. ...
That method allowed a 2-order-of-magnitude faster high-resolution image reconstruction with equivalent image quality compared to state-of-the-art algorithms. ...
METHODS
Problem formulation The classical image degradation model of SISR defines the LR image ( Y ∈ R I/r1×J/r2×K/r3 ) as a downsampled (with rate r 1 = r 2 = r 3 = r in our application) and blurred ...
