Abstract: A method, system and computer program product for region proposals are disclosed. The method includes generating a map of a video frame by calculating a plurality of pixel-level values. Each pixel-level value corresponds to a respective one of a plurality of pixels and provides an associated indication of how likely the respective one of the plurality of pixels forms part of a particular object of interest.

Abstract: Methods for detecting anomalies in a geographic area include receiving, from an electronic computing device, expected relationship data indicating expected relationships between a plurality of entities within the geographic area; detecting the plurality of entities within the geographic area; generating observed relationship data indicating observed relationships between the plurality of entities; identifying the expected relationships between the plurality of entities based on the expected relationship data; determining that a given observed relationship between two entities of the plurality of entities is likely to represent an anomaly based on the expected relationship data; and providing an electronic notification to a safety officer, the electronic notification indicating that the given observed relationship is likely to represent the anomaly.
