Video Object Segmentation through Spatially Accurate and Temporally Dense Extraction of Primary Object Regions
In this paper, we propose a novel approach to extract primary object segments in videos in the ‘object proposal’ domain. The extracted primary object regions are then used to build…

High-Speed Photo-Modulated Spindt Cathode for FELs
SRI International is integrating a Spindt-type field-emission source with a high-mobility GaN photoconducting semiconductor switch (PCSS) to develop cathodes capable of producing Ampere-level currents in the picosecond pulse regime.
