Hi,
A standard practice is to apply tapering then padding (with zeros).
AKA windowing. In Scilab:
https://help.scilab.org/docs/6.0.1/en_US/window.html
2D windows can be built from these 1D profiles.
By the way, it could be useful to upgrade window() in order to become
able to generate
such 2D or N-D windows without external postprocessing.
Wish now reported as bug 15694
<http://bugzilla.scilab.org/show_bug.cgi?id=15694>.
