Re: [SIP-devel] new interf_demo + pbs

[Ricardo F. <rf...@if...>]

Hi!

I've been busy having many exams here at the University,
especially a hard one about partial differential equations.
But this will enable me to learn and implement more advanced methods in
SIP, namely those based on level sets for segmentation and filtering.

Soon I'll incorporate your last developments and continue with SIP.

regards,
Ricardo.
