•Survey of the most relevant approaches for detecting stationary foreground objects.•Kinds of stationary foreground objects in the literature.•Typical challenges to overcome, and popular datasets to test the strategies.•Descriptions of the algorithms applied in the different stages of the strategies. Detection of stationary foreground objects (i.e., moving objects that remain static throughout several frames) has attracted the attention of many researchers over the last decades and, consequently, many new ideas have been recently proposed, trying to achieve high-quality detections in complex scenarios with the lowest misdetections, while keeping real-time constraints. Most of these strategies are focused on detecting abandoned objects. However, there are some approaches that also allow detecting partially-static foreground objects (e.g. people remaining temporarily static) or stolen objects (i.e., objects removed from the background of the scene). This paper provides a complete survey of the most relevant approaches for detecting all kind of stationary foreground objects. The aim of this survey is not to compare the existing methods, but to provide the information needed to get an idea of the state of the art in this field: kinds of stationary foreground objects, main challenges in the field, main datasets for testing the detection of stationary foreground, main stages in the existing approaches and algorithms typically used in such stages.
