Lawrence Livermore National Laboratory




Summary

The workshop will examine current opportunities and challenges for the signal and image sciences community. The forum is intended to enable a productive exchange of ideas on state-of-the-art technologies and recent developments. With the goal of sparking interesting discussions, we encourage submission of intermediate results from ongoing projects or recent conference papers. To enhance technical exchange between participants, we are also encouraging posters for this Workshop. The event is open to all engineers, scientists, and students with an interest in the signal and image sciences who are employed at LLNL only this year.

The workshop will be held in-person at the Livermore Valley Open Campus (LVOC), 643 R1400, and requires pre-registration. Coffee and snacks will be provide for morning/afternoon breaks.

We are monitoring the current development and guidelines provided by LLNL to make sure we are following best practices with respect to COVID. Please see current guidelines on the [Return to New Normal] website.
