Despite eminent progress in recent years, various challenges associated with object tracking algorithms such as scale variations, partial or full occlusions, background clutters, illumination variations are still required to be resolved with improved estimation for real-time applications. This paper proposes a robust and fast algorithm for object tracking based on spatio-temporal context (STC). A pyramid representation-based scale correlation filter is incorporated to overcome the STC’s inability on the rapid change of scale of target. It learns appearance induced by variations in the target scale sampled at a different set of scales. During occlusion, most correlation filter trackers start drifting due to the wrong update of samples. To prevent the target model from drift, an occlusion detection and handling mechanism are incorporated. Occlusion is detected from the peak correlation score of the response map. It continuously predicts target location during occlusion and passes it to the STC tracking model. After the successful detection of occlusion, an extended Kalman filter is used for occlusion handling. This decreases the chance of tracking failure as the Kalman filter continuously updates itself and the tracking model. Further improvement to the model is provided by fusion with average peak to correlation energy (APCE) criteria, which automatically update the target model to deal with environmental changes. Extensive calculations on the benchmark datasets indicate the efficacy of the proposed tracking method with state of the art in terms of performance analysis.

The article addresses the problem of bridging the divide between the present-day technological advancement, primarily in the field of normative legal and technical regulation of fire safety, and the qualification of persons, authorized to regulate relations in fire safety assurance (hereinafter — “Authorized persons”) in the context of transition of the state regulation of fire safety relations from an obsolete standard target model to a new analytical and scenario-based (risk-oriented) target model used to make decisions in the area of control over the safe condition of the technosphere in view of a sudden increase in the dynamics of sociocultural processes.The Education and Research Supervision Unit of the State Fire Academy of the EMERCOM of Russia (the Ministry for Civil Defense, Emergencies, and Elimination of Consequences of Natural Disasters), responsible for the drafting of suggestions concerning the implementation of point 10, Minutes № 1 of the meeting of the workgroup of EMERCOM of Russia on May 20, 2019 “Regarding the arrangement of interaction with the management authorities of the institutional firefighting service of executive federal authorities and organizations”, has developed “The list of milestones of professional culture for the persons responsible for regulating relations in the field of fire safety for the period of transition from a standard target model to the risk model of controlling, supervisory, and authorization-related activities” (hereinafter — “the List”).This List represents a basic set of conceptual professional milestones, whose attainment enables authorized persons to re-focus their conscience from an obsolete standard paradigm, used to make decisions in the area of fire safety, to a new risk-oriented one.Given the focus of this article, it defines some, or the most significant, milestones of professional risk-oriented culture of authorized persons.
