| Abstract | We present the theory behind TOD (the Temporal Object Discoverer), a novel unsupervised system that uses only temporal information to discover objects across image sequences acquired by any number of uncalibrated cameras. The process is divided into three phases: (1) Extraction of each pixel's temporal signature, a partition of the pixel's observations into sets that stem from different objects; (2) Construction of a global schedule that explains the signatures in terms of the lifetimes of a set of quasi-static objects; (3) Mapping of each pixel's observations to objects in the schedule according to the pixel's temporal signature. Our Global Scheduling (GSched) algorithm provably constructs a valid and complete global schedule when certain observability criteria are met. Our |
