Intelligent image recognition system for detecting abnormal features of scenic spots based on deep learning

Abstract

To monitor the scene anomaly in real-time through video and image and identify the emergencies, try to respond quickly at the beginning of the emergency and reduce the loss. This paper mainly focuses on the realization of the image recognition system for the anomalous characteristics of tourism emergencies. The problem is to study the number of people in the scenic spot based on scenic spot monitoring. The video-based population anomaly monitoring method has improved the AUC index of the W-SFM method by 0.423, and the AUC has increased by 0.0844 compared with the optical flow method; Degree-enhanced algorithm (BCOF), by grasping the micro-blog data related to the scenic spot, comprehensively predicts the overall comfort of the current tourists in the scenic spot, and establishes a tourist state expression model. Compared with the BN algorithm and the NEG algorithm, the BCOF algorithm is the accuracy and the recall rate of tourists in the scenic spots was improved by 14% and 18% respectively. The image recognition system of tourism emergency anomaly was established, and the early warning model of tourism emergency based on group intelligence perception was used to implement early warning on scenic spots. Monitoring, can achieve an overall accuracy of 83.33%, the model has a strong predictive ability, and achieves a scenic spot Real-time monitoring of events.

Intelligent recognition system of converter station operation text based on computer image acquisition

“…The text of converter station operation includes the combination of Chinese characters, Chinese characters and numbers, Chinese characters and letters, Chinese characters and numbers and letters, and so on. How to quickly and accurately recognize and detect characters is the key of intelligent character recognition system, which requires the characteristics of high recognition accuracy and high recognition accuracy of intelligent character recognition system [20] . Now, the recognition and detection system detects a batch of handwritten character images with the same number of different categories, and makes a comparative test under the condition of the same number of handwritten characters, as shown in Table 2.…”

Analysis of the Spatial Pattern and Influencing Factors of Tourist Attractions in the Yellow River Tourism Belt

“…Research avenues in this field differ between domestic and international scholars. International research predominantly revolves around visitor numbers at attractions [1] and the intelligent evolution of tourist sites [2] . In contrast, domestic research places greater emphasis on the spatial distribution of attractions and their temporal dynamics.…”
