The purpose of the Radio Camera Initiative (RCI) was to develop a highly optimized high-throughput end-to-end pipeline for near real-time flagging, calibration and imaging with very large-N radio interferometer arrays (thousands of antennas) such as the Deep Synoptic Array (DSA), proposed to the 2020 Astronomy Decadal Survey, as well as Phase 2 of the Square Kilometre Array (SKA). This effort occurs against the backdrop of an explosive growth period in the software and algorithms used for radio astronomy motivated by the SKA, VLA/ngVLA, ALMA, MeerKAT, ASKAP, LOFAR, MWA, HERA, LWA, GMRT, EVN and VLBA etc. In the initial exploratory phase of the RCI, we invited luminaries worldwide to present the cutting edge techniques being used for flagging, calibration, imaging and data processing in radio astronomy and beyond.
