Lawrence Livermore National Laboratory



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 and is free of charge.


Among the broad range of technical topics slated are computed-tomography reconstruction and analysis, signal- and image processing and control in support of the National Ignition Facility, radiation detection and isotope ID, electromagnetic sensing methods, adaptive optics, novel sensing modalities (gravity gradiometry, biomedical and geophysical sensing), computer vision and video analytics, and machine learning and pattern analysis.
