AbstractThis study mainly analyzed the improved three-frame difference algorithm for the identification of active targets in the intelligent substation. The improved three-frame difference algorithm introduced the Gaussian mixture background algorithm on the basis of the traditional three-frame difference method. The Gaussian mixture background algorithm, traditional three-frame difference method, and improved three-frame difference method were tested in the actual substation. The results showed that the improved difference method eliminated the non-target background more thoroughly when recognizing the moving target in the image; in the tested video, the improved algorithm had the highest precision and recall ratios for the active target in the video. To sum up, the improved three-frame difference method can more accurately and effectively identify the active targets in the monitoring video, so as to provide an effective support for the unmanned monitoring of intelligent substation.

The smart teaching mode overcomes the shortcomings of traditional teaching online and offline, but there are certain deficiencies in the real-time feature extraction of teachers and students. In view of this, this study uses the particle swarm image recognition and deep learning technology to process the intelligent classroom video teaching image and extracts the classroom task features in real time and sends them to the teacher. In order to overcome the shortcomings of the premature convergence of the standard particle swarm optimization algorithm, an improved strategy for multiple particle swarm optimization algorithms is proposed. In order to improve the premature problem in the search performance algorithm of PSO algorithm, this paper combines the algorithm with the useful attributes of other algorithms to improve the particle diversity in the algorithm, enhance the global search ability of the particle, and achieve effective feature extraction. The research indicates that the method proposed in this paper has certain practical effects and can provide theoretical reference for subsequent related research.
