We present theoretical results on the random wavelet coefficients covariance structure. We use simple properties of the coefficients to derive a recursive way to compute the within- and across-scale ...

Images captured at night often suffer from flare artifacts, which are characterized by their diverse shapes and strong contamination. Removing these flares and restoring the details in the ...

In this note, we observe that the dimension function associated with a wavelet system is the trace of the Gramian fibers of the shift-invariant system generated by the negative dilations of the mother ...
