Abstract
The paper considers algorithmic and software for early fire detection based on smoke detection from video sequences generated by a static video camera. To detect areas with smoke, an algorithm has been developed that allows you to select such areas on video frames that are characterized by a number of features: the presence of a stable directional movement, compliance with the color characteristics of smoke, and a decrease in the energy value of highfrequency components relative to the background model. The feature of the algorithm is a step-by-step spatiotemporal analysis of candidate areas, which provides satisfactory computational costs and real-time operation on modern computing tools for high-resolution video frames. The algorithm is implemented using the functions of the OpenCV computer vision library and multi-threaded processing. The features and main functionality of the software implemented as a stationary application are given. The results of experimental studies on the evaluation of the efficiency of the algorithm and its speed are presented.
