An approximation algorithm for the least overlapping p-Frame problem with non-partial coverage for networked robotic cameras
Abstract— We report our algorithmic development of the pframe problem that addresses the need of coordinating a set of p networked robotic pan-tilt-zoom cameras for n, (n > p)...
