When
, the iterative framework refers to the iterative seislet thresholding:

(3) |
where
denotes a thresholding operator with a threshold
,
and
are a pair of forward and inverse seislet transforms.
can be either a soft-thresholding operator:

(4) |
or a hard thresholding operator:
|
(5) |
In this paper, all the examples are based on soft thresholding. I iteratively decrease the threshold
in the seislet domain during the iterations.
